Solar flux of 1000 W/m2 is incident on the top side of a plate whose surface has a solar absorptivity of 0.9 and an emissivity of 0.2. The air and surroundings are at 25°C and the convection heat transfer coefficient between the plate and air is 20 W/m2 K. Assuming that the bottom side of the plate is insulated, determine the surface convection and radiation heat fluxes, and the steady-state temperature of the plate.
