A horizontal semitransparent plate is uniformly irradiated from above and below, while air at T 300 K flows over the top and bottom surfaces, providing a uniform convection heat transfer coefficient of h 40 W/m2 K. The absorptivity of the plate to the irradiation is 0.40. Under steady-state conditions measurements made with a radiation detector above the top surface indicate a radiosity (which includes transmission, as well as reflection and emission) of J 5000 W/m2 , while the plate is at a uniform temperature of T 350 K. C Determine the irradiation G and the emissivity of the plate. Is the plate gray ( ) for the prescribed conditions?
