1-128 A thin metal plate is insulated on the back and ex- posed to solar radiation on the front surface. The exposed sur- face of the plate has an absorptivity of 0.7 for solar radiation. If solar radiation is incident on the plate at a rate of 700 W/m² and the surrounding air temperature is 10°C, determine the sur- face temperature of the plate when the heat loss by convection equals the solar energy absorbed by the plate. Take the convec- tion heat transfer coefficient to be 30 W/m² °C, and disregard any heat loss by radiation.
