7.39 A long, thin metal plate is hung vertically after a heat treating process. The plate, of width W= 0.2 m, ver- tical dimension of 3 m, and an initial temperature of T-320°C, is cooled by atmospheric air of velocity V=4 m/s and Toe-30°C. Determine the initial rate of heat loss from the plate if the air is in parallel flow over the plate. Account for heat loss from both surfaces of the thin plate. Determine the initial rate of...

Hot carbon dioxide exhaust gas at 1 atm is being cooled by flat
plates. The gas at 220°C flows in parallel over the upper and lower
surfaces of a 1.4-m-long flat plate at a velocity of 1.8 m/s and
the flat plate surface temperature is maintained at 80°C. The
properties of CO2 at Tf = (220°C + 80°C)/2 = 150°C are k = 0.02652
