2 of 4 I Review I Constants I Periodic Table In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is Tin = 20°C and the temperature outside is Tout = 0°C. The walls and uppermost ceiling of a typical house are supported by 2 × 6-inch wooden beams (kwood = 0.12 W/(mK)) with fiberglass insulation (kins = 0.04 W/(mK)) in between. The true depth of the beams is actually 5.625 inches, but we will take the thickness of the walls and ceiling to be Lwall = 18 cm to allow for the interior and exterior covering. Assume that the house is a cube of length L= 9.0 m on a side. Assume that the roof has very high conductivity, so that the air in the attic is at the same temperature Part A How much heat per second H (= Q/AT) is lost from the house due to heat conduction?

Needle ball bearings, D=5-mm, H=26-mm, are heated up to 1200 K in a heat treatment furnace where the micro-structure is transformed from pearlite to austenite. As soon as taken out of the furnace, they are quenched in water having T=286 K and h=174 W/m2K to transform the micro- structure from austenite to martensite. Find the time required for cooling the bearings to T=326 K. Assume the bearings are perfectly cylindrical and made of AISI 347 Steel. H
