A plane brick wall, 25 cm thick, is faced with 5 cm thick concrete layer. If the temperature of the exposed brick face is 70 °C and that of the concrete is 25°C, find out the heat lost per hour through a wall of 15 m x 10 m. Also, determine the interface temperature. Thermal conductivity of the brick and concrete are 0.7 W/mK and 0.95 W/mK respectively. 6,
