A 4m x 4m flat plate maintained at a constant temperature of 80°C is subjected to parallel
flow of air at 1 atm, 20°C, and 10 m/s. The total drag force acting on the upper surface of the
plate is measured to be 2.4N. Determine the average convection heat transfer coefficient,
and the rate of heat transfer between the upper surface of the plate and the air.
The properties of air at 20°C and 1 atm from tables, are:
p=1.204 kg/m', C, =1.007 kJ/kg.K,
Pr = 0.7309
Answer: h= 46.54 W/m².°C,
