The old style heating uses steam (or hot water) in an radiator to heat a room in winter time. A radiator can be considered as a vertical surface 0.5 meter high and 1 meter wide. The surface temperature of the radiator is 70 ? C , and the room temperature is 18 ? C. How much heat is transferred to the room by radiation heat transfer, if the emissivity of the surface is 0.5? How much heat is transferred to the room by free convection in the laminar region using the simplied equation for air?
