Consider the base plate of a 850W household iron with a thickness of L= 0.5 cm, base area of A = 150 cm², and thermal conductivity of k= 25 W/m°C. The inner surface of the base plate is subjected to uniform heat flux generated by the resistance heaters inside. When steady operating conditions are reached, the outer surface temperature of the plate is measured to be 85°C. Disregarding any heat loss through the upper part of the iron, a. express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the plate, b. obtain a relation for the variation of temperature in the base plate by solving the differential equation, c. evaluate the inner surface temperature. d. Base plate - 85°C Fig. 1- Base Plate
