Water is pumped 14.5 km from a reservoir at elevation 30 m to another reservoirat elevation 70 m. The steel pipeline connecting the reservoirs has a nominal diameter of 1400mm (the actual inside diameter is 1372 mm) with C = 90. If the flow is 1.18 m3/s, the pumpingefficiency is 82%, and electricity costs $0.14/kWh. Assuming that the density of water is 1000kg/m3, what will be the monthly power bill?
