5. Water is pumped from a reservoir to a storage tank at top of a building by means of a centrifugal pump. There is a 200-ft difference in elevation between the two woter surfaces. The inlet pipe at the reservoir is 8.0 ft below the surface, and local conditions are such that level is substantially constant. The storage tank is vented to the atmosphere and the liquid level is maintained constant. The inlet pipe to the storage tank is 6 ft below the surface. It is desired to maintain a flow of water in to the tank of 625 gal/min. Water temperature is 68 F. If the pump-motor set has an overall efficiency of 60 percent, and the total loss of energy due to friction in the piping system is 35 ftlbf/Ibm, what would the pumping costs be in dollars per day if electricity costs $0.08/kWhr?
