Q2. A thin metal plate is insulated on the back and exposed to solar radiation on the front surface. The exposed surface of the plate has an absorptivity of (a=0.7) for solar radiation. If solar radiation is incident on the plate at a rate of 550 W/m² and the surrounding air temperature is 10°C, determine the surface temperature of the plate. Take the convection heat transfer coefficient to be 25 W/m² K and disregard any heat loss by radiation.
