5.10 Figure 5.15 shows a thin flat plate used as a heating element. Air at 10C and atmospheric pressure flows over the plate with a velocity of 4 m/s. Steam temperature is 160C and the thermal conductivity of the plate is very high. Calculate the total rate of heat transfer to the air per unit depth.
