QUESTION $3$:

Heat is generated in a large plate $)=(0\mathrm{.}8\frac{W}{m}C$ at a rate of $50(0)0\frac{W}{m^{\text{'}}}$ the plata is $25sm$ thick. The outside surfaces of the plate are exposed to ambient air at $299C$ with a cemeriotice: heat transfer coefficient of $25\frac{W}{m}2C.$ Model the wall using four heat tranter elementes and determine;

a$)$ the temperature distribution in the wall

b$)$ heat flux, and

c$)$ heat loss from the right side of the wall surface.
