Question

As shown in the figure below, a pump lifts water through a 100-mm diameter
ductile iron pipe (friction factor f = 0.0251) from a lower to an upper reservoir. If the difference
in elevation between the reservoir surfaces is 10 m, and the pump performance curve is given
by H = 15 – 0.1Q2, where H is in m and Q in L/s.
a. Determine the system head curve (relationship between TDH and Q) assuming the
entrance and exit loss coefficients are both 1
b. Estimate the flow rate through the system
c. If the minimum NPSH for this case is 1.5 m, determine the maximum height above the
lower reservoir that the pump can be placed (assuming that the atmospheric pressure

Pa=101 kPa, specific weight of water ? = 9.79 kN/m3, and the water vapor pressure Pv
= 2.34 kPa).
