Assume that the solar collector system of Problem 7.2 has an average efficiency of 60% during the month of January and 68% during the month of June. On average, how many gallons of supply water at 70°F could be heated to 120°F by the system each day during each month?
What will be an ideal response?
For January, total solar energy intercepted by the collectors each day
Considering the efficiency of the system is 60% in January,
amount of water required per day
For June, total solar energy intercepted by the collectors each day
Considering the efficiency of the system is 68% in June,
