A 32 inch diameter pump handling 22000 GPM flow of water coming from an atmospheric tank storage is running at 1170 rpm. The water temperature can be taken at 25 C. The suction line is 20 meter long at 6 inch diameter. The pump suction is 0.4 meter above ground level. The tank storage is elevated on a 1 meter high platform. Assume friction factor of 0.02. Specific Gravity of water at 25 C is 0.9967. NPSH required is 34 ft. Determine: A) NPSHA in terms of feet, B) Will cavitation occur, yes or no? C) BHP D) the specific speed., E and G) if new speed is 900 rpm with same impeller diameter, determine the new flowrate in GPM and new head in ft?

Turpentine flows by gravity from tank 1 to tank 2 through 24 m
of 1.5-inch diameter commercial steel pipe. Both tanks are open to
atmosphere. The tanks are large, so assume that the level of
turpentine in both tanks remains the same with time. The level of
tank 1 is 15 m higher than the level of tank 2 (indicated on the
schematic as z1 and z2). There are two standard 90° elbows and one
open gate valve in the...

The piston diameter of a certain hand pump is 0.7 inch. The
manager determines that the diameters are normally distributed,
with a mean of 0.7 inch and a standard deviation of 0.005 inch.
After recalibrating the production machine, the manager randomly
selects 21 pistons and determines that the standard deviation is
0.0044 inch. Is there significant evidence for the manager to
conclude that the standard deviation has decreased at the a=0.10
level of significance?
What are the correct hypothesis is...

A 12-inch diameter cast iron pipe conveys 1500 gpm of liquid at
an industrial facility. At one point in the pipe, call it point A,
a gage indicates that the pressure is 45 psi. Another point in the
pipe, call it point B, is 175 ft downstream of point A (measured
along the pipe).
(a) Determine the head loss (ft) between points A and B if the
liquid is: (i) SAE 30 oil at 60°F; (ii) water at 60°F.
(b)...

The water flow rate for a particular sprinkler is 19 gpm. The
water must be projected at least 24 feet in radius. The sprinkler
is mounted 11 feet above the ground and is aimed at an angle of 26

leave the sprinkler? What diameter (inches) should the opening be
to achieve this velocity?
Water Velocity =_______ ft/s
