Question: Consider an opaque horizontal plate that is well insulated on its back side. The irradiation on the plate is 2500 W/m2 of which 500 W/m2

Consider an opaque horizontal plate that is well insulated on its back side. The irradiation on the plate is 2500 W/m2 of which 500 W/m2 is reflected. The plate is at 227°C and has an emissive power of 1200 W/m2. Air at 127°C flows over the plate with a heat transfer convection coefficient of 15 W/m2 ∙ K. Determine the emissivity, absorptivity, and radiosity of the plate. What is the net heat transfer rate per unit area?
