Q1 What is the role of power factorcorrection in energy consumption? A1 Krupa Shah , B.techBachelor of Technology in Electronics and Communications Engineering, K JSomaiya Institute of Enginee…Answered Thu The purpose of power factorcorrection is to make the energy consumption process easier. PFC aids in the reduction of excessive electricitybills. The load-carrying capabilities will be improved by improving the PFCfeatures. The demand charges for the power system will also be reduced as aresult of power factor correction. Here are 5 ways, how powerfactor correction helps in energy consumption Avoid Penalties cause due to high power factor The employment of high-load induction components for operational purposesin any manufacturing unit increases reactive power, for which utility companiescharge a power factor penalty if it falls below the allowable threshold foryour home or business. As a result, the easiest way to save money is to install power factoradjustment capacitors. The power factor penalty on utility bills can beeliminated with these capacitors. It also aids in the reduction of your energyuse. Demand Charges Will Be Reduced The measured amount of KBA will be larger than the demand for KW if thepower factor is low. As a result, power firms will bill for demand measured inKVA or KW. The demand charge will be reduced, and the electricity bill will bereduced depending on energy use, by improving the power factor and seekingcorrection. Enhance Load Carrying Potential You can ensure that inductive load-bearing circuits decrease excessivecurrent flow by integrating capacitors for PFC. Because of the higher powerfactor, the circuit will be able to handle higher power loads. It will alsosave money on the expense of expanding the distribution line to meet increasedcapacity needs. You will save a lot of money on your energy bills in the long term if youinstall power factor correction capacitors. Enhanced Voltage When the load has a poor power factor, it consumes a lot of current,which raises the energy consumption and the bill. As the line current rises,the voltage drop rises with it, causing voltage degradation in certainequipment. You can expect a reduction in voltage drop and an increase inequipment voltage if you seek the inclusion of passive power factor correctionfilters. Improved Power Quality You can expect improved power quality at home and in the workplace byusing active power factor adjustment filters. Because the energy usage will bemore refined, you will pay less than you would have paid with low powerfactors. It lowers kw/h power usage and eliminates unnecessary power charges. These are just a few of the benefits of PFC in terms of paying the bestprice for refined energy usage. If you are going to install power factorcorrection in your home or business, you can contact Powermatrix for a powerfactor correction capacitor. Q2 Is "schnockered" a Britishword? If so, what does it mean? A2 Claire Jordan Degreein biology and folklore; programmer, shop owner, secretary on newspaper21h No, the word you’re searchingfor is “snookered”. Snooker is a tabletop ball game similar to pool orbilliards. In the game, a snooker is a difficult position in which a player cannot directly aim thecue-ball at any other ball but has to bounce it off the side cushions, and tosnooker an opponent is to put them in that position. By extension, therefore,to be snookered is in general to be backed into a position you can’t easily getout of, similar to but slightly less drastic than being check-mated. Q3 What can we do with coconut wastes? A3 Naman Jain Enthusiastand Avid Explorer Apr 7 Coconuts are produced in 92countries worldwide on about more than 10 million hectares. Indonesia, Philippines and India account for almost 75% ofworld coconut production with Indonesia being the world’s largest coconutproducer. A coconut plantation is analogous to energy crop plantations, howevercoconut plantations are a source of wide variety of products, in addition toenergy. The current world production of coconuts has the potential to produce electricity, heat, fiberboards,organic fertilizer, animal feeds, fuel additives for cleaner emissions,eco-friendly cutlery, health drinks, etc. The coconut fruit yields 40 % coconut husks containing 30 % fiber, withdust making up the rest. The chemical composition of coconut husks consists ofcellulose, lignin, pyroligneous acid, gas, charcoal, tar, tannin, andpotassium. Coconut dust has high lignin and cellulose content. The use of coconut husks orwaste are for the production of board material and has a number of advantages: The method is sustainable and environmentally friendly. The residualmaterial of the coconut is used in its entirety. It is a good alternative towood and helps to prevent deforestation. During production, glue and chemicalagents do not need to be added. Furthermore, the production is CO2 neutral. It is inexpensive. The gluethat has to be added whenboards based on wood fibre are made contributes to one third of the totalproduction costs. Glue is not required to process coconut husk into boardmaterial. It can form an extra sourceof income for farmers in developing countries. The board material that is madefrom coconut husk can beused for all kinds of applications, for example, in the construction sector,such as wallboards, frames and similar. The material is intended for both localconsumers and for export, for example, the furniture industry. The study isfunded by the Common Fund for Commodities (CFC), a collaborative projectbetween 100 countries that supports and assists agricultural projects. Q4 Why does Bengaluru look richer thanChennai? A4 Naveen Subramanian Livedin Chennai, Tamil Nadu, India Wed It's the same way of asking whyLondon city doesn’t have skyscrapers as Dubai. Even after a few hundred years, I guess the people of London will tryto keep their aesthetic value unchanged. That’s because London as a city has a traditional valuethat’s closely knitted with European history of planning and architecture.Those aesthetic values can’t be recreated. Now if you take Chennai - it’snot one designated city. It’s a combination of 3 districts - Chennai,Kancheepuram, and Thiruvallur. It has expanded and will keep expanding. Bangalore is for the migrantpopulation - people flood to work and stay, leave the city which will bereplaced with a new set of migrants. People who stay in Bangalore forgenerations are too low. But Chennai is different - it wasnever meant to be planned for a migrant population. On the other hand, it’s a city of destination for migrants fromthe South of TN. People flood to live here, settle down for generations. Peopleown properties here even if they don’t continue to live here. You can see these types of typical houses in Mylapore that are more than100 years old And these, who are more than 50 years old And these ….These types of buildings are preserved for their aestheticvalue and are passed on across generations. One of my friends spent almost 3crores to renovate such type of his old building. Constructing a new building with modernarchitecture will cost less cheap, but he chose not to. His family has atradition that he wanted to retain. So spent doublethe cost just to retain its aesthetic value. The new urban and semi-urban areas of Chennai will have multi-storybuildings that are meant to facilitate migrating middle-class population. Thenative Chennai - mostly the north and central Chennai - is very musttraditional and aesthetic. It’s because of these people. who live here, hasn'tmoved out. They continued to live here across generations Now with regards to Bangalore - ofcourse it’s a city with a history oftraditional culture and architecture. However, sinceIT boom in 2000, the Karnataka StateGovt intends to promote it as a city that competes with NY and Sydney both interms of economy and livelihood. The govt wants Bangalore to be identified as“IT hub” of India. The city did undergo major transformation as it scaled up interms of economy. Here the key is “ Transformation” - the city transformed quicker whileit’s traditional buildings exists paralelly. Bangalore as a city has anecessity to look richer and modern. It is its USP. The entire tech economy of Bangalore is dependent on its modern cityplanning and architecture. The city attracts international clients and skillssets. The multi-cultural nightlife of Bangalore is a product of itsmulticultural city planning. The city’s economy has to compete with NY andSydney. They need to come up with city attractions to lure internationalclientele. Chennai doesn’t have suchcommitments. There is no majortransformation out of investor’s expectations. It’s a city of its own. It’s anidentity of its own. The city’s economy is more domesticated andself-sustainable. The city planning is subjected to local demands and needs. Answering the original question - Why does Bengaluru look richer thanChennai? The key is “transformation” , acity undergoestransformation when the govt decides to transform it. Karnataka state govtbanked on tech economy of Bangalore, and did stir major transformations. WhileChennai has been a manufacturing hub outside the city limit - hence the cityexpanded in terms of geographic areas but did not undergo westernization oftransformation within the city on it’s own. Bangalore City planning is aproduct of investor's demand.Chennai City planning is a product of localdemand. Edit — Bangalore hastraditionally asthetic architecture too. But the Karnataka govt is interested to promote Bangalore more as an IThub than a traditional city. My answer is to address the mindset of outsideworld that compares Bangalore City culture with that of chennai. It's notintended to offend the interest of native banglore residents.

A5 Gopala Krishnan,former Assistant General Manager 1996-2004 at Department of Telecom(1966-2004)Answered just now I am from Chennai, India. Now it is summer. First appliance coming in thelist of energy consumption is Air-condition units used during day and night. Second one isbore-well motor andsump motor operated during morning and evening. Perhaps third can bethe 65 watts fans used.Fourth one is the fridgestwo numbers in most homes especially inKerala. Q6 Why are bacteria classified underplants? A6 Ken Saladin Formerprofessor of histology (microscopic anatomy)Updated 1h I was taught in my childhood that everything could be classified as “animal, vegetable, ormineral.” The great pioneering taxonomist Linnaeus first proposedthese three categories in 1735 (Regnum Animale, Regnum Vegetabile and RegnumLapideum), and then subdivided each of those into kingdoms and smallercategories. My mother played a game with me in which she’d name objects atrandom and I’d have to say which “kingdom” it belonged to. Of all of these, bacteria certainlyweren’t minerals and they didn’t seem like animals, so they were dumped intothe Plantae by default. Ithink protozoans were put in the Plantae if they were green and Animalia ifthey were not. Mushrooms and other fungi, too, were classified as plants, butnot any longer. It was a classification based on ignorance, not knowledge.Scientists at the time did the best they could with what little they had in theway of observational tools. And now that we have molecular and genetic tools of unprecedented sophistication,and knowledge beyond science’s prior imagination, the classification system Ilearned in high school and college and passed on to my own students in the1970s and ‘80s—kingdom, phylum, class, order, family, genus, species—is alltopsy-turvy with clades and strange new names I’m glad, in retirement, I don’thave to teach. UPDATE: I am puzzled by why the question was changed after I answered itfrom the original “Why were…” to “Why are….” If it had been written that wayoriginally, my answer probably would have begin, “They’re NOT.” It’s strangehow some people become more committed to wrong ideas after they get correctinformation Q7 Is there any place in world wherethere is no gravity? A7 Rohit Virmani KnowsEnglish Apr 10 There are some places on thisplanet where gravity does not work. Here is a list of 5 such places: -1- The golden rock, Myanmar: After looking at the rock, one can have a feeling that it can fall downanytime but it has been sitting like this for more than 2500 years. -2- Reverse waterfall inEngland(Hayfield in Derbyshire Peak District) It sounds unbelievable but it is true that there a waterfall which flowsin reverse manner which means from down to up. The river Kinder flows downwardto a certain point and then it starts flowing upwards. -3- Oregon Vortex, the house ofmysteries: There is a broom over here which never lies down irrespective of themanner in which it is kept and balls roll even on the flat surfaces. Manypeople have used special devices to find out the reason of strange occurrencesbut nobody has succeeded till date. -4- Hoover dam, Nevada Built on the border on two American states- Nevada and Arizona. It is anarch shaped dam which is constructed on the Black Canyon of the Colorado riverand it is 726.4 ft. tall. In order to see whether gravity works over there ornot, a person needs to carry out a simple experiment. When the water from thebottle is dropped in the dam, instead of flowing downwards, the water flowsupwards -5- Reverse waterfall in India: There is a reverse waterfall in India as well and it is just 3 hrs fromMumbai. This waterfall is in Naneghat which is pretty close to Junnar, Pune,and the reason behind water flowing upwards is the strong wind which forceswater to flow in the upward direction. Q8 How do you clean the dust out ofyour laptop? A8 Gopala Krishnan,former Assistant General Manager 1996-2004 at Department of Telecom (1966-2004)Answered just now I am from Chennai, India. It is summer and dust falling is more. One ofthe things that can be done is- make it a habit to work in computer in an air-conditioned room .This can reduce dust on laptop more than 50%. 2nd one is to clean the key board and display with a soft cloth. Thiswill also reduce dust to 40%. A small percentage of dust must go inside key board. This cannot beremoved. Best possible is to keep the laptop closed while not working. One can clean the outside of laptop with a good cloth, if needed with aslightly wet cloth. Key board is cleaned in service centres after applying acleaning liquid. This also can be tried. After a few years , key boardwith all cleaning appear old and display become dim, say after 5–6 years. It is high time to purchase a new laptop. Saveyour data to an external memory before disposing old computer. Replacement of key board andLED display may rarely improve the appearance. As far as possibleavoid using Laptop in non air-conditioned room. Computer for home use isavailable around Rs 35000–00 in Chennai shops. Those using Laptops and conversant with it’s working aregenerally affordable to purchase a new one- A general statement. Q9 How much unit does a washing machineconsume in 1 hour of usage? A9 Veronica Graunwolf ,former World Traveller/Butcher, Baker, Candlestick Maker (1966-2018) AnsweredJun 14, 2019 I assume you mean watts of electricity per minute/hour. That depends onyour machine and its options. Different makes use different amounts. Your machine or users manual shouldbe able to tell you that. 2ND ANSWER -YajnaFuel, studied ChemicalEngineering & Enery at Hadas High School (1978) Answered Jun 14, 2019 Self help is good.Set timing for 1hr,switch off all other appliances.Get out, lock the door and takereadings on your electric meter. You will get 2o odd values, conclude, integrate,subdivide the data as per your convenience, comfort etc Q10 Are our bodies literally under constantattack from bacteria? A10 Ken Saladin Formerprofessor of histology (microscopic anatomy)1h I would not say “attack.” They are seldom pathogenic(disease-causing) and many are beneficial, even necessary to our health. Nevertheless, they are always there—on the skin, in the hair, in the airwe inhale, in what we eat and drink. Our skin oils and perspiration (even theperspiration we’re not aware of) have a mild acidity and antibacterial proteinsthat keep the bacteria under control. Our mucous membranes in the respiratory and digestivetract also are loaded with antibacterial agents as well, and relativelyfew species of bacteria can survive the stomach acid. A few kinds, of course,do—hence the human problems with botulism, salmonella, and peptic ulcer. Bacteria of our large intestineare mostly benign (harmless) or even “friendly forces.” All the above QA are from Quora website on 15-04- 2022.
