Problem 156P

Problem 156P

A 2.4-m high 200-m2 house is maintained at 22°C by an air-conditioning system whose COP, is 3.2. It is estimated that the kitchen, bath, and other ventilating fans of the house discharge a houseful of conditioned air once every hour. If the average outdoor temperature is 32°C, the density of air is 1.20 kg/m3, and the unit cost of electricity is $0.10/kWh, the amount of money “vented out” by the fans in 10 hours is

(a) $0.50

(b) $1.60

(c)$5.00

(d) $11.00

(e) $16.00
