The following data were recorded when a centrifugal pump worked at its maximum efficiency: Q =
40 /ps ; Manometric head developed = 25 m; Input shaft horse power = 11.9 W. What is the non-
dimensional specific speed of the pump it it was running at 1500 rpm? (May adopt the following (all
in S.I. units):
g¹/4 = 1.77, g/2² = 3-132, g/=5.544,
√√21.414,5 = 2.236 and 10 = 3.162)
Use the following given values to solve problems, unless otherwise stated.
Ywater = 9790 N/m³ = 62.4 lbf/ft°; g = 9.81 m/s? = 32.2 ft/s²; 1 hp = 550 lbf-ft/s = 746 Watts
Problem-1
Water is pumped from the
large tank through a uniform diameter pipe (d = 3 in.)
and exits as a free jet (refer figure-a). The plot of the
flowrate (Q) versus pump-head (hp) is a straight-line
graph that passes through points (3, 16) as shown in
figure-b. If the pipe friction head loss is, hf = 7V:/2g,
where V is the average fluid velocity in the pipe, find a)
the equation that relates hp and Q; b) flowrate and c) If
the pump is 75% efficient, what horsepower is needed
to drive it? Assume steady, incompressible flow. Ignore
kinetic energy correction factor (a).
