Q1 Mr Gopalakrishnan is a scholar who is an authority on all under the SUN who will waste by socretical type Q &A (that is what is his thinking like ; or else will he ask whether fridge will cool the room and immediately answer, how can it? ) [ Am I wrong when I call him a Joker?) Q2 What a silly Q & A on a plane stopping while taxiing. The greatest answer is that a machine is harnessing like an athlete!! The taxiing is taking position at potential ground energy when certain switches and engines are not kept at the optimum. ON GROUND. Then on runway takeoff starts with raising the engine; it is not harnessing; it is a system; race cars do that; so why does a plane stopping become such a gossip in quora? Thank GOD there may be questions in future, why Gopoalakrishnan sits , stands, bends, takes bath only at that time etc etc. Q3 Another Q why alarm works? Let it not work . So what? Why does Gopalkrishnan's heart work, while he is sleeping? Q4 Which fridge bears that write up sir? To my best of knowledge all stabilizers are kept only overboard in all homes. And no fridge installer till yesterday, placed the stabilizers, if so needed, outside the fridge. Near the air vent there will be warnings not to block the vents. Notlike don't place stabilisers and don't sit near it etc. If there is no better stuff, declare a week holiday sir. Q5 Do you have any air curtains at your home sir? It is generally for Pothys and Nallis. The efficiency against the natural power is doubtful, in deploying these machines. The physics behind is F-MV2,
Imagine rolling two balls at each other for a head-on collision. After they hit, which way they roll depends on a simple law of physics <https://science.howstuffworks.com/innovation/scientific-experiments/newton-law-of-motion.htm>: F=MV2, or "force equals mass times velocity (squared)." This means that a small ball rolling fast can potentially overpower a large ball rolling slowly. The same concept goes for the air curtain. The force of the air blowing from the curtain has to be strong enough to overpower and turn back the force of the air coming from the outside. If your giant, open warehouse door is constantly getting pummeled by strong winds, you'll need a hefty air curtain -- one that blows a lot of air with great velocity. The other thing to take into account is the direction of that velocity. You might think that an air curtain would most effectively fight horizontal winds with its own horizontal winds. But that's not really the case. When air is blown directly out the door for a head-on collision with other air (like those two balls we mentioned above), much of the power of the air is lost over distance. Instead, air curtains direct their flow of air mostly downward toward the floor of the doorway. The system must blow hard enough to ensure the air is still traveling at the needed velocity as it reaches the bottom of the doorway, and that the velocity is also stronger than the velocity of the outside, inrushing air. As such, the curtain acts like a wall that outside air comes toward and then bounces off of. So if the outgoing is 20 miles per hour speed, the incoming must be 20+ so that the heavy force sends back the low force. So the air curtain is more efficient than the swinging doors. But involves extra cost and doubtful integrity. In summer the outside air will be hotter than the inside low power air venting out; then air shall condition by working harder to soften the incoming hot air. Commercial organisations who had to keep open the doors all the time try this. A blow fan can do this job. A gatekeeper in the star hotel, who opens the door and closes also does the same thing. Cost effectiveness depends. KR IRS 28 6 23 NB Please no one reads all these according to Mr Gopalakrishnan Thanks for not reading these. Also thanks for reading Gopalkrishnan so avidly.
