Air conditioning on a university campus is provided by chilled water (10oC) pumped through a main supply pipe. The pipe makes a loop 5 km in length. The pipe diameter is 0.75 m and the material is steel. The maximum design volume flow rate is 0.65 m3/s. The circulating pump is driven by an electric motor. The efficiencies of pump and motor are ?p = 85 and ?m = 85, respectively. Electricity cost is 14?/(kW.hr). Determine (a) the pressure drop, (b) the rate of energy addition to the water, and (c) the daily cost of electrical energy for pumping.
