Consider the base plate of a 1200-W household iron that has a thickness of L = 0.5-cm, base area of A= 300-cm', and thermal conductivity of k = 15-W/m-C". The inner surface of the base plate is subjected to a uniform heat flux generated by the resistance heaters inside, and the outer surface losses heat to the surroundings at T = 20°C by convection. Taking the convection heat transfer coefficient to be h = 80-W/m--°C obtain an expression for the...
