Use the finite element software FEHT to show the temperature distribution in the walls of a two dimensional furnace shown below. The furnace is at 750 F and the convective heat transfer coefficient inside and outside of the furnace are 40 and 10 Btu/ft.F.hr respectively. Calculate the amount of heat lost to the ambient and determine the maximum and minimum temperatures in the metal and the insulation? To evaluate the warm-up time of the furnace, assume it is initially at ambient temperature and suddenly exposed to 750 F gas. Approximately how long it will take to reach steady state? Submit your results along with tech memo and a rough hand calculation to confirm the finite element results. Furnace internal dimensions: 2' x 4' Furnace walls: Insulation: Stainless Steel, 1" thick Calcium Silicate, 4" thick
