Question

You have a kiln where theinterior is a cube with an edge length of 30 cm. The walls of the kiln are made of an insulating refactory, and are 10 cm thick. The thermal conductivity of the refractory is .06 W/mK. The interior of hte kiln is at a temperature of 1250 degrees C, and the kiln is surrounded by still air at 35 degres C. For these conditions:

a) Estimate the surface temperature of the vertical walls next to the still air in degrees C

b) Estimate the heat flux through the vertical walls in W/m^2
