The air at local atmospheric pressure (1 atm) and 27oC flowing over a flat plat with a velocity of 50 m/s. The plate maintain a temperature of 227oC. The plate is 1.5 m width and 0.3 m long and the air is flowing in the 0.3 m longside. Determine the heat transfer coefficient, the convection heat transfer rate from the top of the plate, and the drag force on the plate.
