Reference no: EM13510099

On a cold night the temperatures of the two surfaces of a glass windowpane in a house are 7.8° C on the outer surface and 8.0° C on the inner surface when the air temperature is 0° C outside and 18.6° C inside. The glass is 3.33 mm thick. (The thermal conductivity for glass is 0.8 W/m-C°.)

(a) Find the rate at which heat is conducted through the glass per square meter of window area.

(b) Find the value of the convection coefficients for the heating of the inner surface of the glass and for the cooling of the outer surface.
