Q2 Why are cargo ships eventually scrappedinstead of continually repaired and rebuilt? A2 Erika Fernandez, Loves Boating52m Cargo ships arelarge vessels that carry goods and materials across the oceans. They are usually made of steel and have a lifespan of 25 to 30 yearsbefore they become uneconomical to operate. Repairing andrebuilding a cargo ship can be very expensive, especially if the ship is oldand damaged. Thecost of maintenance, fuel, insurance, crew, and port fees can exceed therevenue generated by the ship. Scrapping a cargo ship can provide a source of income for the owner, asthe steel and other materials can be sold for recycling or reuse. The demand forcargo shipping can fluctuate depending on global market conditions, tradepolicies, consumer preferences, and other factors. Sometimes,there may be an oversupply of cargo ships in the market, which can lower thefreight rates and profitability of the operators. Scrapping a cargoship can reduce the supply and increase the demand for shipping services, whichcan benefit the remaining operators. The regulation of cargo shipping can change overtime to address various issues such as safety, security, pollution, emissions,and labor standards. These regulations can impose new requirements or standardsfor cargo ships, such as installing new equipment, upgrading existing systems,or complying with certain rules. Some cargo ships may not be able to meet theserequirements or standards due to their age or design and may face penalties orrestrictions if they continue to operate. Scrapping a cargo ship can avoidthese problems and allow the owner to invest in newer and more compliantvessels. Also, the innovation of cargo shipping canintroduce new technologies or designs that can improve the performance,efficiency, or capacity of cargo ships. These innovations can createcompetitive advantages or disadvantages for different types of cargo ships inthe market. Some cargo ships may become obsolete or outdated due to their lackof innovation or adaptation and may lose their market share or value. Scrappinga cargo ship can enable the owner to replace it with a newer and moreinnovative vessel that can meet the changing needs and expectations of thecustomers. Q3 What do you mean by 124 units per yearin refrigerators? A3 Venkateswara Swamy Swarna,FormerScientist, Metallurgist, Quality / NDT Manager at Department of Atomic Energy,India (1967–2008)2y 1 unit is 1 kwh - 1 kilowatt load run for one hour. Therefrigerator does not consume power all the time. Most of the power consumptionis from the compressor (say 100 watts). And if that runs for 8 hours aday, the energy consumption would be 800 watthours per day and the consumptionin one year of 365 days would be 292 units. So, thevalue of 124 units is approx. 1/3rd of an unit per day…very energy efficientrefrigerator (and also probably a small sized one)… There is a Starrating - units with more stars consume less electricity. Thus a 5 star refrigerator ismuch better than a 3-star unit but would also cost more to buy. 2ND answer-Prasanna Bhalerao,M. Sc. inElectronics & Physics, Fergusson College, Pune Thu It means that therefrigerator will consume 124 KWh electricity per year. Your electricity unitsare measured in KWh. 1 KWh = 1 unit. (Pleasedon't go by these numbers. They often deceive on the low side. ) Q4 Can you replace a circuit breakerwithout turning off the main breaker? A4 Tutuer,National Certificate L4 inElectrical Engineering, Toi-Ohomai Institute of Technology (Graduated 2016)Jul26 Technically yesbut in practise NO!I’vebeen an electrician for 26 years and the tutor I had said you would get people who try to get you to work on live circuits and thatyou NEVER have to do it. There is always away to isolate the circuit upstream from where you are working on it, and itgood practice have 2 points of isolation but not really essential. If any body could do it - I could. Of the thousandsof circuits I've worked on, I've never intentionally worked on a livecircuit. Never have. Never will. Q5 Why does ice water taste better thanroom temperature water? A5 RI Shohag,9h If someone givesyou a glass of warm water when you're thirsty, chances are you won't like thetaste very much. On the other hand, if someone offers you a glass of ice water,it's a completely different story. That said, what might bethe reason behind this change in flavor that accompanies a change intemperature? Increases the feeling of rehydration Recent researchshows that certain brain tissues and structures detect dehydration before youstart to feel thirsty. This prompts you to reach for a glass of water—and thephysical act of drinking tells your brain that you're rehydrating. This sensationis amplified when the temperature of the drink is colder or warmer than themouth and throat, as the fluid stimulates the nerves that respond totemperature and touch. Tells your brainthat water is clean and safe In the naturalworld, clean, fresh water from rivers and streams is often very cold,while stagnant, germ-prone water tends to be warmer. Thus, the humanpreference for cold water may be related to an evolutionary need to preventdiseases caused by germs, bacteria and viruses. Suppresses unpleasant tastes Extremetemperatures, whether cold or hot, influence how sensitive your taste buds areand what flavors you can taste. High temperatures agitate the molecules andmake them more perceptible by taste and smell, while low temperatures stabilizethe molecules. This means that a glass of cold water will mask unpleasant flavors much better thanone at room temperature. All the above QA are from Quora website on 05-08- 2023.
