A thin flat plate 3 m × 2 m is hanging freely in air. The temperature of surrounding is 24°C. Solar radiation is falling on one side of the plate at the rate of 432 W/m2. What should be the convective heat transfer coefficient (in W/m2 -°C), if the temperature of plate is to remain constant at 30°C?
