Consider a house that is maintained at 22°C at all times. The walls of the house have R-3.38 insulation in .SI units (i.e., an L/k value or a thermal resistance of 3.38 m2 · °C/W). During a cold winter night, the outside air temperature is 6°C and wind at 50 km/h is blowing parallel to a 4-m-high and 8-m-long wall of the house. If the heat transfer coefficient on the interior surface of the wall is 8 W/m2 · °C, determine the rate of heat loss from that wall of the house. Draw the thermal resistance network and disregard radiation heat transfer.
