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. W₁ = kW
