Atypical heat pump may heat a home at a rate of 40,000 btu/hr. if a heat pump has a coefficient of performance of 3.6, how much power does it need to run, in hp? according to delmarva power, the average cost of electricity is 14 cents per kilowatt hour. how much would it cost to run the heat pump all winter (say, 2000 hours)?

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
