It is desired to pump a flow rate of 20 I/s through a IO-cm-diameter pipe 1000 m long to a location whose invert is 30 m above the water source from which the pump is drawing. Assume that the water temperature is 20°C and the pipe is new cast iron. Select the "best" pump in terms of efficiency and horsepower using Figure 9.18.
