The concrete slab of a basement is 11 m long, 8 m wide and 0.20 m thick.
Question:
The concrete slab of a basement is 11 m long, 8 m wide and 0.20 m thick. During the winter, temperatures are nominally 17°C and 10oC at the top and bottom surfaces, respectively. If the concrete has a thermal conductivity of 1.4 W/m. K, what is the rate of heat loss through the slab? If the basement is heated by a gas furnace operating at an efficiency of T/f = 0.90 and natural gas is priced at Cg = $0.01/MJ. What is the daily cost of the heat loss?
