question

Air at one atm. and 90°F moves at 140 ft/sec across a flat plate of length 3 ft. The temperature at the sur-face of the plate is 450°F. For a 1 ft. width, deter-mine the heat loss from the entire plate, and also the heat loss from the laminar and turbulent sections of the boundary layer. Then, assuming that the boundary layer is completely turbulent, calculate the heat loss.
