A house is being built. The contractor states that the cost to install electricbaseboard heat will be $2,480. The contractor also states that a forced air,heat pump system will be 21⁄4 times as much. How much will the heat pumpsystem cost?
To maintain a dwelling steadily at 68°F on a day when the outside temperature is 40°F, heating must be provided at an average rate of
300 Btu/min.
Determine the electrical power required, in kW, to deliver the heating using:
(a) electrical-resistance heating,
(b) a heat pump whose coefficient of performance is 3.5,
(c) a reversible heat pump operating between hot and cold reservoirs at 68°F and 40°F, respectively.
Part A
Determine the electrical power required, in kW, to deliver the heating using electrical-resistance heating.

A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h. There are 10 lightbulbs in the room, each1
with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 kJ/h. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
