Question

A furnace is constructed with 20 cm of firebrick (k=1.36 W/m-K), 10 cm of insulating brick (k=0.26 W/m-K), and 20 cm of building brick (k=0.69 W/m-K), the inside surface temperature is 650oC and the outside air temperature is 32oC, the heat loss from the furnace wall is 0.56 kW/m2.

Determine the following:

A.)The unit convective coefficient for air.

B.)The temperature 25 cm in from the outside surface.
