Chapter 1 Basics of Heat Transfer 1-109E A flat plate solar collector is placed horizontally on the roof of a house. The rate of heat loss from the collector by convection and radiation during a calm day are to be determined. Assumptions 1 Steady operating conditions exist. 2 The emissivity and convection heat transfer coefficient are constant and uniform. 3 The exposed surface, ambient, and sky temperatures remain constant. Properties The emissivity of the outer surface of the collector is given to be 0.9. Q & Solar collector T sky = 50 ° F Air, 70 ° F Analysis The exposed surface area of the collector is
