Calculate the rate of heat loss (in W) through the wall. Follow-up question to Question 1, calculate the temperature (in °C) of the interior surface of the wall. Follow-up question to Question 1, calculate the temperature (in °C) of the exterior surface of the wall. Note: Round the answers to 2 decimal places.
Question 1: The exterior wall of a building consists of 100 mm thick face brick (k = 0.9 W/m∙K), 40 mm thick polystyrene insulating board (k = 0.036 W/m∙K), 125 mm thick concrete block (k = 1.8 W/m∙K) and 15 mm thick interior gypsum board (k = 0.18 W/m∙K). The inside and outside convective heat transfer coefficients are 6.5 W/m2∙K and 22.5 W/m2∙K, respectively. The outside air temperature is -5°C and the inside air temperature is 20°C. The wall is 3 m high and 15 m long. Calculate the rate of heat loss (in W) through the wall.
