Consider a 20 cm thick granite wall lining an industrialfurnace. The temperature of the inner surface of the wall is 50 °C.The outer face of the wall is exposed to flowing air at 22 °C witha heat transfer coefficient of 15 W/m2.K. Calculate the heat fluxthrough the wall. Is it safe to touch the outer face withoutthermally insulated gloves? Granite has a thermal conductivity of2.79 W/m.K.
