1. An 85 percent-efficient pump is used to increase the pressure of water in a 10-cm-diameter pipe from 120 to 800 kPa. What is the required horsepower of the pump for a flow rate of (a) 0.015 m3=s, (b) 20 L=s, and (c) 4000 gal/h?

2. A 90 percent-efficient turbine accepts water at 400 kPa in a 16-cm-diameter pipe. What is the maximum power output if the flow rate is (a) 0.08 m3=s, (b) 0.06 m3=s, and (c) 0.04 m3=s? The water is emitted to the atmosphere.
