Question

A water supply system draws from a river at an elevation of 800-feet and delivers the water to a storage reservoir at elevation 820-feet. The supply pipeline is a 1000-foot long, 10-inch diameter, cast iron pipe. A single pump with the pump characteristic curve in Figure 1 is used to fill the reservoir.
Determine:
a) Sketch the system described in the problem statement.
b) Inlet and outlet minor loss coefficients, cite your source of minor loss coefficients.
c) The roughness ratio for use in the Jain equation(s), cite your source of roughness height.
d) The energy equation for the system.
e) The pipe Reynolds number for discharges of 1200, 1600, 2000, 2400, and 2800 gallons-per-minute.
f) The pipe friction factors for discharges of 1200, 1600, 2000, 2400, and 2800 gallons- per-minute.
g) The fitting loss coefficients for discharges of 1200, 1600, 2000, 2400, and 2800 gallons-per-minute.
h) The system loss for a discharge of 1200, 1600, 2000, 2400, and 2800 gallons-per- minute. Plot the system loss values on the supplied pump curve.
i) The operating discharge for the system using the supplied pump curve.
j) The electric power supplied to the pump to lift the water at the operating point.1
1Assume the efficiency on the pump curve is representative of the wire-to-water efficiency.

Parts H,I, and J please.
