A 1m x 1 m square solar collector is placed on the roof of a house. The collector receives a solar radiation flux of 800 W/m2. Assuming that the surroundings act as a blackbody at an effective sky temperature of 30?C, calculate the equilibrium temperature of the collector(a) Assuming its surface is black and the conduction and convection are negligible, and(b) Assuming that the collector is horizontal and loses heat by natural convection.GIVENA square solar collector on the roof of a houseCollector dimensions = 1 m x 1 mSolar flux on collector (qs) = 800 W/m2ASSUMPTIONSSteady state conditionsThe surroundings act as a blackbody at an effective sky temperature (T2) = 30?C = 303 KThe surrounding air temperature (T??) = T2 = 303K
