Question:

Consider a 20 cm thick granite wall with a thermal conductivity of 2.79 W/m·K. The temperature of the left surface is held constant at 50°C, whereas the right face is exposed to a flow of 22°C air with a convection heat transfer coefficient of 15 W/m²·K. Neglecting heat transfer by radiation, find the right wall surface temperature and the heat flux through the wall.

Granite k= 2.8 W/m-K T = 22°C T= 50°C h= 15 W/m2-K 20 cm
