2. A pump delivers 30o C water from a supply reservoir to an
elevated storage tank at a discharge rate of 120 litres/sec. At
this discharge the manufacturer’s data indicates the net positive
suction head (NPSH) for the pump is 6.0 m. The water surface
elevation difference between the reservoir and the tank is 45.0 m.
The total length of pipe between the two is 150.0 m, 10.0 m of
which is located on the suction side of the pump....

Cooling water (T= 20 C) is pumped from a reservoir to rock
drills on a construction job using the pipe system With Diameter D
= 10 cm. The flow rate must be 130 m3/h and water must leave the
spray nozzle at 30 m/s. Nozzle discharge at the 100 m above
reservoir (a) Calculate the minimum pressure
needed at the pump outlet. (b) Estimate the
required power input if the pump efficiency is 70 percent.

A pump takes water at 60°F from a large reservoir and delivers
it to the bottom of an open elevated tank 25 ft above the reservoir
surface through a 3 inch ID pipe. The inlet to the pump is located
10 ft below the water surface, and the water level in the tank is
constant at 160 ft above the reservoir surface. The pump delivers
150 gpm. If the total loss of energy due to friction in the piping

A centrifugal pump delivers water at rate of 0.22
m3/s from a reservoir at a ground level to another
reservoir to height 'h' through a vertical pipe of 0.2 m diameter.
Both are open to atmosphere. Power input to pump is 90 kW and it
operates with 75% efficiency . f=0.004 use g=9.8 m/s2
density=1000kg/m3. Find 'h'.

has been concerned lately about the amount of money required
to
repair
malfunctioning pumps. These costs are sums over and above the
amounts
spent for
routine maintenance. When asked what factors they thought might
affect
the mean
monthly repair costs, employees suggested the age of the pumps and
the
number of
hours of operation. The following information was collected.
