Reconsider Prob. 2–83. Using EES (or other) software, investigate the effect of the heat transfer coefficient on the highest and lowest temperatures in the plate. Let the heat transfer coefficient vary from 20 W/m²·K to 100 W/m²·K. Plot the highest and lowest temperatures as a function of the heat transfer coefficient, and discuss the results.

Data from problem 83

Consider a large 5-cm-thick brass plate (k = 111 W/m·K) in which heat is generated uniformly at a rate of 2 × 10⁵ W/m³. One side of the plate is insulated while the other side is exposed to an environment at 25°C with a heat transfer coefficient of 44 W/m²·K. Explain where in the plate the highest and the lowest temperatures will occur, and determine their values.
