A room in a house has a floor made entirely of concrete which is 200 mm thick. The lower surface of the concrete in contact with the ground has a temperature of 10°C and the upper surface, in contact with the living area has a temperature of 15°C. The floor is square and has sides 10m x 10m
a) Calculate the rate at which thermal energy ia conducted through the concrete. Assume the thermal conductivity of concrete is 0.750W/mK.
b) The temperature of thr carpet/concrete interface. The rate of conduction for both conductors are the same and the thermal conductivity of the carpet is 0.06W/mk.
c) The rate at which thermal energy is conducted through the two layers.
