- A glass window in a house has an area of 0.67 m^2 and a thickness of 2.4 mm. The temperature inside the house is 21 C, and the outside temperature is 0 C. How much heat is lost through the window in 1 hour (3600 s) due to conduction? Use 1.0 W/(m x C) for the thermal conductivity of the glass. How much heat is lsot through the window in 1 hour (3600 s) due to raditaion? ( assume the temperature of the rntire glass is 21 C for this probelem). Which mode of heat transfer (condutciton vs. raditiaon) accounts for the greater amount of heat loss?The weather channel reported that the current temperature at the town of Fairbanks Alaska is 50 °F. What is the corresponding value of this temperature on the Centigrade scale?An engineer who is working on the heat transfer analysis of a house in English units needs the convection heat transfer coefficient on the outer surface of the house. But the only value he can find from his handbooks is 22 W/m2·K, which is in SI units. The engineer does not have a direct conversion factor between the two unit systems for the convection heat transfer coefficient. Using the conversion factors between W and Btu/h, m and ft, and °C and °F, express the given convection heat transfer coefficient in Btu/h·ft2·°F.
