ease show clear workings and state all assumptions made Electrically heated draw batch furnaces are commonly used in the heat treatment industry. Consider a draw batch furnace front made of a
20-mm-thick steel plate with a thermal conductivity of
25(W)/(m)*K. The furnace is situated in a room with a surrounding air temperature of
20\deg Cand an average convection heat transfer coefficient of
10(W)/(m^(2))*K. If the inside surface of the furnace front is subjected to uniform heat flux of
5k(W)/(m^(2))and the outer surface has an emissivity of 0.30 , determine the inside surface temperature of the furnace front. ( 25 points). Note that if you got an equation to the
4^(th )power, you would need a scientific calculator or EES to solve it - don't try to solve it by hand.
