A composite wall separates combustion gases at 2600 °C from a liquid coolant at 100 °C, with gas- and liquid-side convection coefficients of 50 and 1000 W/m^2K. The wall is composed of a 10-mm- thick layer of beryllium oxide on the gas side and a 20-mm-thick slab of stainless steel on the liquid side. The contact resistance between the oxide and the steel is 0.05 m^2K/W. What is the heat flux of the composite wall? Sketch the temperature distribution from the gas to the liquid.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
