CULTURAL QA04-2022-24 BEING A COMPILATION THERE MAY BE ERRORS
Q1 Changed AC pipes andrefilled gas, still there's no cooling after a few days, what could be theproblem? A1 Agosh Kumar, formerMechanical Design, Piping, HVAC, Structural Design Answered Jan 26, 2018 Since the pipes are changed there would be some leakage at the joints. Reduced cooling effect can be areason for many probable problems ranging from the pressure drop to faultycompressor. But before that check if there is dust accumulated in the evaporator fanassembly. Further it isadvisable to have a check with the local AC repair technician. The cooling effect will only work when therefrigerant charge is exactly matching to the manufacturer specifications. Unless it can be disastrous as exploding of thecompressor. 2ND ANSWER-AnandteerthDeshpande, Mech. Engineerwith experience in HVAC and passionate in energy audits. Answered Feb 6, 2018 You have replied to my comment that the AC technician replaced the piping because it wasleaking. After doing this, you say that the machine is not givingcooling effect. This only means that the leakage was not the root cause to yourunit’s poor performance. It is possible that the pressure testing andvacuuming of the piping has not been done properly. The service team is supposed to hold vacuum andascertain the total absence of moisture in the piping. You need to answer ifthe technician has done the pressure testing and later vacuuming properly. It is also possible that thetechnician has not done the charging of the refrigerant adequately. He may haveoverdone it also. Secondly, the AC unit may not function properlyif the heat exchangers i.e., coil of the indoor unit and condenser are notcleaned properly or are not able to exchange heat. In any case, please speak to the owner of the firm which did servicing tocome in person to rectify. You can demand your service free of cost if you arenot satisfied with the service. 3rd answer-GopalaKrishnan, former AssistantGeneral Manager 1996-2004 at Department of Telecom (1966-2004)Answered just now I have read all other answers before answering. A company technician will go to changing copper tubes andrefilling of gas AS LAST RESORT. It is not mentioned how old is theAC unit. There is wear and tear, and after say, 5 years though AC may function,cooling can be less on account of this. Another factor not checked isthe input voltage. Stabilizer functioning not checked. Loose connection interminals are not checked. Further the starting and runningcapacitors can be weak.They not only consume more current affect the functioning also. Last point is the compressor terminal check. If theconnection is not tight compressor may not function properly and there willbe no cooling Q2 What happens to crudeoil if we never dig it out? Would it get deeper and deeper, and what happenswhen it reaches magma? A2 Paul Noel FormerResearch Scientist 6 Level 2 UAH Huntsville Al. (2009–2014)Apr 5 You are thinking the wrong direction. Oil floats upin the earth to the surface of the earth. It wasdiscovered in Oil Creek Pennsylvania for the first commercial oil well becauseit floated up in the creek. The Creek was named oil creek because ofthis floating up. The magma is actually the source of the oil asMethane is evolved by complex processes of a nuclear reaction deep in the earth and the hydrogen from that reaction involves itselfwith carbon on the way up. When it gets mid way up in the continents itencounters a massive amount of metallic oxides Iron and Calcium Oxide. Theseand many more react catalytically with the methane causing it to undergodehydrogenation synthesis and polymerizing into oil. When it comes up in thesurface it along with water comes up. The water is from the freed hydrogen andoxygen of the reactions in the rocks. On the surface it becomes oxidized quiterapidly into Carbon Dioxide CO2. It goes through many lifecycles with plants and animals that causes loss of the CO2 in inefficiency torelease Oxygen. Most ofthis happens in the ocean. This is what evolves the oxygen on the earth givingus our atmosphere and oceans. The result of life is that the sea plankton andother sea life produce carbonate shells and the CO2 is settled out to thebottom of the ocean. Over time as the crustal processes cause the crust tothicken it becomes more buoyant and it pops up showing up as great limestonemountains. The buoyancy is compared to the magma in the mantle of the earth. If we don’t dig it up it stillcomes up. Over time it will all come up. Mankind has no influence on theappearance of oil on the earth. If you look at the bottom of the Gulf of Mexico you will see a pockmarked area around much of it. That is actually Asphalt Volcanoes where the oilcomes up. There is like 50,000 barrels of oil that naturally seeps up in USAwaters every day. It is in fact illegal for the oilmen to drill and stop thoseseeps because so much sea life depends on the oil. Nearly 1/3 of all the lifein the world’s oceans owes its breeding ground to this oil and these seeps inthe Gulf of Mexico. Oil is not the death of life on earth, it andnatural gas literally are the very cause of life on earth. Q3 Are carrots fruits orvegetables? A3 Lucia Garcia Worked atHospitals Thu Botanically speaking, a fruit is the mature ovary of a plant thatcontains the seeds used for reproduction. A vegetable is any part of a plant that is edible and does not containseeds, such as stems, roots, leaves, flower etc. Because carrots do not containseeds, it is the root of the plant, so carrots are considered vegetables, morespecifically, Carrots Are Root Vegetables. Generally, fruits are only suitable for eating raw, although carrots canalso be eaten raw, but cooked carrots are more nutritious than raw carrots. Carrots are the best source of carotene, and a medium-sized carrotcontains about 4.5 mg of carotene. If you eat raw carrots, the body's absorption rate of carotene is onlyabout 10%.Cooked or fried carrots, the absorption rate of carotene can reachmore than 90%.Since carotene is a fat-soluble vitamin, adding edible oil canincrease the bioavailability of carotene. After carotene enters the body,about 50% will be converted into vitamin A under the action of enzymes. Vitamin A can enhance andprotect vision, maintain normal visual function, and is very beneficial to eyehealth. Q4 Is America the onlycountry where you can legally buy guns? A4 Claire Jordan Degreein biology and folklore; programmer, shop owner, secretary on newspaper Apr 7 As far as I know there’s no country in the worldwhere you’re not allowed to own a gun, except possiblythe Vatican and Antarctica. In some places it’s actually mandatory - forexample there’s at least one place in the far north of Europe where you’re notpermitted to leave town without a gun, because of all the polar bears. Here in the UK, for example, you can own a tank or an antiaircraft gun,although you can’t fire them except at an army firing range, and you can own apunt gun which I believe is illegal in the US. But there are strict controls on who can own a fullyautomatic rifle or a concealable handgun. Q5 Why hasn't Africa developed aswell as other continents? A5 Geoffrey Widdison I knowexactly enough about money to be dangerous. Updated Sat There are a ton of historical reasons, but the dominant ones boil down tothe fact that sub-Saharan Africa never developed a native system of intensiveagriculture. Agricultureis what led to food surpluses and sedentary populations, which led to large,concentrated populations, which led to specialization, which led to invention,which led to, which led to, which led to…. So, why didn’t agriculture develop like it did in Eurasia, and NorthAfrica? In Ryan North’s wonderful book “How to Invent Everything” one of hisrecommendations to a stranded time traveler is to look around when you firstarrive, and see if you can spot one of these: If you can, he says, congratulations. Your civilization is playing on‘easy’ mode. Jared Diamond devotes a whole chapter in “Guns, Germs and Steel” to thispoint. In the historyof the world, only 14 large mammals have been fully domesticated, and evidencesuggests that those are the only ones that are practical to domesticate. Only 5of those have ever been important to farming (the cow, the pig, the sheep, thedonkey, and the horse). As it happens, all five of those are nativeto Eurasia. Due to issues like climate and disease, they oftenhave trouble even surviving in sub-Saharan Africa. There are lots of large mammals in Africa, but none of them have everbeen domesticated. The zebra, for example, seems like it should be very similarto horses, but they have fundamental attributes that make them poor candidatesfor domestication. Every time it’s been tried, it’s eventually failed. In modern times, domesticated animals seem either so commonplace or soobsolete that we tend to forget how stupidly overpowered they were in a worldwhere human muscle had been the limiting factor on how much work could be done.And the horse, most ofall. They revolutionized farming, transportation and warfare, to the pointwhere a civilization that had horses would almost always overwhelm acivilization without them. Start one society with horses and one society without, then let thingsunspool for ten thousands years, and the odds are pretty good that the horsepeople are going to be running the show. If it had so happened that horses evolved in Africa, andcouldn’t survive in Europe Or if zebras happened to be domesticable,and horses weren’t, then things might have gone very differently over the lastfew millenia. Development always depends onresources and how they’re used. Eurasia simply had certain biological resourcesthat Africa lacked, and that made a huge difference. Q6 I want to demolish myold house in Chennai. What are the procedures? How do I get my demolitionapproval/order without paying a bribe? A6 Naveen Subramanian Livedin Chennai, Tamil Nadu, India Updated Thu Depends on whether you just want to demolish old building to keep theland vacant, or demolish and reconstruct a building at the same site. If your house is within chennaicorporation limit, all you have to do is consult an architect, draw a blueprintof your existing building, fill in the application form for demolition andsubmit it to local corporation office. There’s a govt fee fordemolition, which depends on the area of your building. It’s usually between Rs 8 per sq ft to Rs 20 persq ft. This is a legal fee, which you need to either submit as DD or payonline. You get your demolition plan approved within 15 to 20 working days. You don’t need to pay any bribe for it Few clarifications reg bribing here Demolition fee is around 15 to 25k (depending on sq ft ) so 10% would bejust Rs 1500–2500, so chances of asking bribe is nil or very low. However bribing does takesplace in many areas Demolition plan along with new building construction plan is entirelydifferent. That's where bribing takes place depending on area, floors and numof kitchen. Here bribe is for new one not the old one to be demolished. However there’s something else you need to consider before demolition. Your existing old house must behaving an EB connection. Youneed to decide whether you’re planning to retain it at your own risk orcompletely close it down. You need to take that separately with the local EBdept. They have their own rules. Because once you surrender your existing connection, you need toreapply as a brand new connection in future and pay new connection charges.Work out which is beneficial for you. If you have a well, you need todecide if you’re closing it down. In case you want to close it, this needs tobe mentioned in the original demolition plan blueprint. There are rules for closing down a waterresource, you need to follow that Collection anddispose of debris - once during demolition you need to plancollection and dispose of debris well ahead you start the work. Dumpiing it on the road willattract a heavy penalty. Handlesafety procedures while demolition. Make sure it doesn’t injure your neighbors. Q7 Did the Egyptiansinvent the color blue? A7 Claire Jordan Degreein biology and folklore; programmer, shop owner, secretary on newspaperApr 11 No, of course not. Blue is a thing which exists in nature. But for some reason blueplant-based dyes tend to be unstable, so that until the invention of artificialdyes, blue clothes tended to fade rapidly to pale grey or white. The Ancient Egyptians came up with a very expensive way ofmaking stable blue paints using ground-up minerals, usually lapislazuli. All the above QA are from Quora website on 24-04- 2022.
