ABE002_QUIZ NO.4

It is the product of the cross-sectional area and the mean forward velocity of the water in the section where the area is measured.

It is an instrument used to measure stream velocity indirectly.

It refers to the height of a vertical column of water.

1 pound per square inch (PSI) of pressure is equivalent to how many feet column of water?

It as a device used to lift water from low elevations to higher points of delivery.

The ___________________ of a pump is the sum of the total static head, the pressure head, the friction head, and the velocity head.

It is the total vertical distance the pump must lift the water.

It is the energy loss or pressure decrease due to friction when water flows through pipe networks.

To minimize the suction pipeline friction losses, the suction pipe should have a smaller diameter than the discharge pipe.

• TRUE

• FALSE

It is the implosion of bubbles of air and water vapor and makes a very distinct noise like gravel in the pump.
