Problem 17 A flat-plate solar collector is [FREE SOLUTION

A flat-plate solar collector is used to heat atmospheric air flowing through a rectangular channel. The bottom surface of the channel is well insulated, while the top surface is subjected to a uniform heat flux (q_{o}^{prime prime}), which is due to the net effect of solar radiation absorption and heat exchange between the absorber and cover plates.
