QUESTION 1
Consider a desired pump operating condition which adds 35 psi at a flowrate
of 500 gpm to water (p= 62 11m/ft²³) Ignore any changes in Kinetic or
potential energy and Tassume isothermal flow C.e. internal energy is constant,
this is the normal assumption we make when analyzing fluid flows
in piping systems). Apply the energy balance only across the pump
with full energy
Balance and simlifying to solve for the pump,
Starting

The
is used to pump water from a lower tank to a higher tank through a total length of
pump
800 m of 150 mm diameter pipe. The difference between the water levels in the two tanks is
8m. Neglecting all losses except friction and assuming that C; = 0.004, find the rate of flow
between the two reservoirs.
[Ans: = 60m/hr]
