A 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 10°C at the top and bottom surfaces. The concrete has a thermal conductivity of 1.4 W/m-K. The basement is heated by a gas furnace operating at an efficiency of 0.90, and natural gas is priced at $0.001/MJ. What is the daily cost of heat loss in dollars?
