Question:
A flat plate solar collector has two glass covers (emmittance = 0.88) a black absorber with ?p = 0.95, mean plate temperature of 140oC and ambient temperature of 10oC, and a wind loss coefficient of 10 W/m2/oC. Estimate the top loss coefficient. If the back of the collector is insulated with 50 mm of mineral wool insulation of k of 0.035 W/mC, what is the overall loss coefficient. (neglect edge losses). The slope of the collector is 30oC.The plate spacing is 30 mm.
