A rectangular plate of 30 cm in length, 25 cm in width and 1 cm in height is suspended horizontally by a thin cable in a room. The plate receives a heat flux at all its faces of 20 W/m^2. Air is blown horizontally in the room at a temperature of 25 degrees and a velocity of 2 m/s. The plate is characterized by an absorbtivity of 0.9, emissivity of 0.8, and the convection coefficient between the a and plate is 10 W/m^2. Calculate in degrees the temperature of the plate assumed to be uniform in steady state conditions
