1.24. Compute the heat loss per day through 100m of brickwall (k =0.15 W/mK), 30 cm thick, if the inner face is at 20°C and the outer face at 10°C. Calculate the amount of oil that must be burnt to compensate for this loss if the heat of combustion is 42,000 kJ/kg and the efficiency of the furnace is 60%.
