Consider an aluminum plate that is insulated on all sides except the top. the exposed plate area is 4m2 with 2m in length and 2m in width, and kept at a constant surface temperature of 350c by a heater placed inside the plate. the plate has an emissivity of 0.6 and an absorptivity of 0.4. if the sun is shining with irradiance hitting the plate of 800 w/m2, and air at 25c is blowing over the plate with a heat transfer coefficient of 150 w/m2, what is the overall heat transfer rate (in watts) from the plate?
