A thin square metal plate, 15 cm on each side is placed in a wind tunnel. Air at 25°C, 101.3 kPa flows over the top and bottom surfaces at 35 m/s. The force required to keep the plate stationary is measured to be 0.057 N. The plate is electrically heated to maintain a constant temperature of 80°C. a) Calculate the drag coefficient. b) Estimate the average heat transfer coefficient using the Chilton- Colburn analogy.
