Chapter 12, Problem 12.127(choose chapter or problem)
Consider a thin opaque, horizontal plate with anelectrical heater on its backside. The front side isexposed to ambient air that is at 20C and provides aconvection heat transfer coefficient of 10 W/m2?K,solar irradiation of 600 W/m2, and an effective skytemperature of?40C. What is the electrical power (W/m2) required tomaintain the plate surface temperature at Ts?60Cif the plate is diffuse and has the designated spectral,hemispherical reflectivity?
