1.	Cooling air travels 10 m distance in 5 sec from point A to point B. Calculate the velocity of the cooling air.(a) 2 m/s(b) 4 m/s(c) 6 m/s(d) 10 m/sThe question was asked in exam.My question is based upon Motors in section Rating and Heating of Motors of Electric Drives
Answer» The CORRECT option is (a) 2 m/s The best explanation: The velocity of the cooling air can be CALCULATED USING the ratio of displacement and TIME. The value of the displacement is 10 m. The value of the velocity is 10÷5=2 SEC.
