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...
