Acomposite wall separates combustion gases at 2400°c from a liquid coolant at 100°c, with gas and liquid-side convection coefficients of 25 and 1000 w/m2 ⋅ k. the wall is composed of a 12-mm-thick layer of beryllium oxide on the gas side and a 24-mm-thick slab of stainless steel (aisi 304) on the liquid side. the contact resistance between the oxide and the steel is 0.05 m2 ⋅ k/w. what is the rate of heat loss per unit surface area of the composite? sketch the temperature distribution from the gas to the liquid
