Your job is to write a program that measures the efficiency of stove-top burners. before using your program, the consumer will place a pan of room-temperature water on the stove (with + gallon of water), record the initial room temperature in units of degrees fahrenheit, turn on the burner, and wait for it to boil. when the water begins to boil, the consumer will record the time in units of minutes it takes for the water to boil. finally, the consumer will look up the power for the burner provided by the manufacturer.

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)?
