Water is drawn into the pump, such that the pressure at the inlet a is 35 kpa and the pressure at b is 120 kpa. if the discharge at b is 0.08 m3/s, determine the power output of the pump. neglect friction losses. the pipe has a constant diameter of 100 mm. take h = 2 m.

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)?
