6.36 A thin, flat plate that is 0.2 m × 0.2 m on a side is ori- = ented parallel to an atmospheric airstream having a velocity of 40 m/s. The air is at a temperature of To 20°C, while the plate is maintained at T, = 120°C. The air flows over the top and bottom surfaces of the plate, and measurement of the drag force reveals a value of 0.075 N. What is the rate of heat transfer from both sides of the plate to the air? 6.37 Atmospheric air is in parallel flow (u. = 10 m/s, T. = 15°C) over a flat heater surface that is to be maintained at a temperature of 90°C. The heater surface area is 0.25 m², and the airflow is known to induce a drag force of 0.15 N on the heater. What is the electrical power needed to maintain the prescribed surface temperature? 6.38 Determine the drag force imparted to the top surface of the flat plate of Example 6.4 for water temperatures of 300 K and 350 K. Assume the plate dimension in the z-direction is W = 1 m.
