Repeat Problem 7.16 for Albuquerque, NM, in July if the water source temperature is 17°C.
Problem 7.16
What is the January solar load fraction for a water-heating system in Washington, DC, using 100 m2 of solar collector if the water demand is 4 m3 /day at 65°C with a source temperature of 12°C? No heat exchanger is used, and the solar collector efficiency curve is given in; the solar collector is tilted at an angle equal to the latitude.
