Question:

Electric heater wires are installed in a solid wall having a thickness of 8 cm and k = 2.5W/m ∙ ºC. The right face is exposed to an environment with h = 50W/m2 ∙ ºC and T∞ = 30ºC, while the left face is exposed to h = 75W/m2 ∙ ºC and T∞ = 50ºC. What is the maximum allowable heat-generation rate such that the maximum temperature in the solid does not exceed 300ºC?
