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 227c and has an emissive power of 1200 w/m2 . air at 127c 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?
