1. A solar collector is 3.0 ft. x 7.0 ft. overall (absorption plate area = 85% of overall area). Plot the efficiency curve of the flat plate collector given the following manufacturer's test data: Test #1 Insolation, I perpendicular to collector = 400 Btu/hr-ft Flow rate through collector = 0.25 GPM of HO t (water in) 110F t (water out) 130F t (ambient air) = 75F Test #2 Insolation, perpendicular to collector = 400 Btu/hr-ft Flow rate through collector = 0 (no flow, stagnation temperature) t (ambient air) = 75F Uc 1.10 Btu/hr-ft-F (Neglect any losses through the collector edges) Transmissivity+Absorptivity, T= 0.75
