The city of Englewood, Colorado, diverts water for

municipal use from the South Platte River at elevation 1610 m

[54]. The water is pumped to storage reservoirs at 1620-m

elevation. The inside diameter of the steel water line is 68.5

cm; its length is 1770 m. The facility is designed for an initial

capacity (flow rate) of 3200 m3

/hr, with an ultimate capacity of

3900 m3

/hr. Calculate and plot the system resistance curve.

Ignore entrance losses. Specify an appropriate pumping system. Estimate the pumping power required for steady-state

operation, at both the initial and ultimate flow rates.
