Thecollector is 5 ft wide and 15 ft long, and the average temperature of the exposed surface of thecollector is 100 °F.a) Determine the rate of heat loss from the collector by convection. Assume it is a calm day whenthe ambient air temperature is 70 °F and the convection heat transfer coefficient on the exposedsurface is 2.5 Btu/h-ft2.°F. andb) Determine the rate of heat loss from the collector by radiation. Assume the effective skytemperature for radiation exchange is 50 °F and the emissivity of the exposed surface of thecollector is 0.9.c) Given these two types of losses, determine how much energy is being collected when theincoming solar radiation is 23,885 Btu/hr.Toky70°F= 50°FSolar collector
