On a cold winter day, the outside temperature is –5.0 °C while the interior of a well-insulated garage is maintained at 20.0 °C by an electric heater. Assume the walls have a total area of 75 m2, a thickness of 0.15 m, and a thermal conductivity of 0.042 W/(m · C°). What is the cost to heat the garage for six hours at these temperatures if the cost of electricity is $ 0.11/kWh?
Note: 1 kWh = 3.6 × 106 J.

During a cold winter, the surface of a river develops a layer of ice of unknown thickness L. Known are the water temperature Ty=4°C, the atmospheric air temperature T=-30°C, and the temperature of the underside of the ice layer To= 0°C. The thermal conductivity of ice is k = 1.88 W/m-K. The convective heat transfer coefficients on the water and air sides of the ice layer are hw = 100 W/m²-K and ha= 50 W/m2-K, respectively. Calculate the temperature of...

The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly windows conduct heat, calculate the rate of conduction in watts through a 2.72 m2 window that is 0.515 cm thick if the temperatures of the inner and outer surfaces are 5.00°C and −10.0°C, respectively. This rapid rate will not be maintained — the inner surface will cool, and frost may even form....
