Solar radiation at 600 W/m2 is absorbed by a black roof inclined at 30?C as shown. If the underside of the roof is well insulated, estimate the maximum roof temperature in 20?C air.GIVENInclined roof, well insulated on the undersideIncline angle (θ) = 30 degreesAir temperature = 20?CSolar radiation absorbed (qs) = 600 W/m2ASSUMPTIONSThe roof behaves as a black body (ε = 1.0)The sky behaves as a black body at 0K
