reservoir and underground piping

Decorative water fountains consist of a water reservoir and underground piping to and from a pump. One such system is shown schematically in Figure P5.69. The inlet line to the pump is 20 m of 16-nominal PVC pipe. The outlet line from the pump is 18 m of 12-nominal PVC pipe. The outlet line leads to the bottom of an annular flow line. The expansion there has a loss value of K=2 based on the kinetic energy in the 12-nominal line. The annular flow passage has a length L=180 cm and is bounded by Do= 30 cm and Di=20 cm. It, too, is made of PVC material. There is a negligible loss at the exit of the annulus; the pressure at that location is atmospheric. What is the pump power required for the flow configuration shown? If the pump-motor combination has efficiency 92%, determine the electrical power requirements. If electricity costs $0.05=kW h, determine the cost of running the fountain for 8 h.
