Consider an opaque horizontal flat plate that is insulated/adiabatic on its bottom side. The irradiation on the plate is 2400 W/m', of which 600 W/m is reflected. The plate is at 200C and has an emissive power of 1500 W/m?. Quiescent air at 30C flows above the plate (10 cm x 10 cm square plate). (1) Determine the emissivity, absorptivity, and radiosity of the plate. (2) What is the net heat transfer rate per unit area?
