A 4 x 8 ft solar collector has water circulating through it at a rate of 1.0 gal per minute gpm while exposed to sunlight with an intensity of 300 BTU/ft2.hr. Fifty percent of that sunlight is captured by the collector as well as heats the water flowing through it. Explain what would be the temperature rise of the water as it leaves the collector?
