The Figure shows a solar collector panel embedded in a roof. The panel, which has a surface area of 24 ft2, receives energy from the sun at a rate of 200 Btu/h per ft2 of collector surface. Twenty-five percent of the incoming energy is lost to the surroundings. The remaining energy is used to heat domestic hot water from 90 to 120°F. The water passes through the solar collector with a negligible pressure drop. Neglecting kinetic and potential effects, determine at steady state how many gallons of water at 120°F the collector generates per hour.
