Solve for the inside surface temperature of the brick wall described in Problem 15.15, but with the additional consideration of radiation from the outside surface to surroundings at 25°C.

Data From Problem 15.15

A 0.20-m-thick brick wall (k = 1.3W/m · K) separates the combustion zone of a furnace from its surroundings at 25°C. For an outside wall surface temperature of 100°C, with a convective heat-transfer coefficient of 18 W/m² · K, what will be the inside wall surface temperature at steady-state conditions?
