It is desired to study the radiation heat loss (or gain) from the surface of an automobile engine. Assume that the engine is a gray opaque convex surface radiating with a heat exchanger for cooling engine coolant (called a radiator) on one side. Assume that the radiator is also a gray opaque flat surface. The engine also radiates with the road surface underneath (a black body), the hood and fender wells (assume these are one reradiating surface) and the firewall (a black body). Construct a circuit to describe these processes and identify all of the radiosities, black body emitters ( Ebi), and resistances in terms of the emissivities, areas, and shape factors.
