Hot air enters a rectangular duct (20cm wide, 25cm high, and 5m long) at 100 kpa and 60 degrees c at an average velocity of 5 m/s. while air flows the duct, it gets cool down (loses energy) so that air leave the duct at 54 degrees c. determine the rate of heat loss from the air under steady condition
