9. A well-mixed fluid is heated by a long iron plate of conductivity k = 12 W/m/0C and thickness t = 0.12m. Heat is generated uniformly in the plate at the rate Qg = 5,000 W/m3. If the surface convection coefficient h = 7 W/m2/0C and fluid temperature is Tf = 45°C, determine the tem¬

perature at the center of the plate 7*c and the heat flow rate to the fluid q using three one-dimensional elements.
