Calculate the minimum pump requirement at pump $2($KWatts$)$ for the given

water distribution system. All pipe segments are $400$ meters long and $750mm$

in diameter with $C=130.$ The pressure head on each pipe is $5\mathrm{.}5$ meters. The

source of water is a lake at elevation $15m.$

The two pumps will supply water at community A and community $B.$

Community $A$ is at elevation $35$ meters while community $B$ is at elevation $80m.$

The design flow for each community should be calculated using Arithrnetic

Method at year $2040.$ Listed below are the population data for each

community.
