Air at 325 K and 70 kPa flows over the upper side of a 1-m-square plate. The upper plate is maintained at a constant temperature of 375 K.
(1) If air flows at a velocity of 5 m/s, calculate the local convection heat transfer coefficient at the trailing edge?
(2) If air flows at a velocity of 100 m/s, what will be the total heat lost by the upper plate.
