A single-stage centrifugal pump has an impeller speed of 1750 rpm. If the flow rate of water is 60 gal/min, determine the expected head.
Choices:
45 ft
60 ft
29 ft
18 ft
2. Water from a reservoir is pump over a hill through a pipe 900mm in diameter and a
pressure of one kg/cm² is maintained at the pipe discharge where the pipe is 85m from the
pump centerline. The pumps have a positive suction head of 5m. Pumping rate or the pump at
1000 rpm is 1.5m³/sec. Friction losses is equivalent to 3m of head loss. What is the head that
should the pump cover for the system?
3. A fire hydrant has an outlet diameter of 630 mm located 1.4
meters above the ground. If the water strikes the ground at a
horizontal distance of 285 meters below the outlet, calculate the

- 3. A centrifugal pump is to be placed above a large, open water tank, as shown in the figure below. Water is pumped at a rate of I cu ft/s. At this flow rate the required net positive suction head, NPSHR, is 15 ft as specified by the pump manufacturer. The water temperature is 80°F and atmospheric pressure is 14.7 psi. Assume that the major head loss between the tank and the pump inlet is due to filter at the pipe inlet having a minor loss coefficient KL.-20. Other losses can be neglected. The pipe on the suction side of the pump has a diameter of 5 in. The water vapor pressure at 80°F is 0.5069 psia and y-62.22 lb/cu.ft. Determine Z1 for cavitation not to occur..
