The concrete slab of a basement is 11 m long and 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, respectively. If the concrete has a thermal conductivity of 1.4
W/mK, what is the rate of heat loss through the slab? If the basement is heated by a gas furnace operation at an
efficiency of 90%, and natural gas is priced at $0.02. MJ, what is the daily cost of the heat loss.
Answer: QLOSS = 4.312 kW, COST = $8.28/day

The EER is defined as the ratio of the cooling capacity of the air conditioner, measured in British thermal units per hour, or Btu/h, to its electrical power requirement in watts. (a) Convert the EER of 10.0 to dimensionless form, using the conversion 1 Btu = 1 055 J. (b) What is the appropriate name for this dimensionless quantity? (c) In the 1970s, it was common to find room air conditioners with EERs of 5 or lower. State how the operating costs compare for 10 000-Btu/h air conditioners with EERs of 5.00 and 10.0.
