ABE (CHAP05 Pump Engineering)

Device used to lift or to transfer liquid from one source to another.

• Pump

• Wind turbine

• Electric motor

• None of the above

Which of the following can be used as a power drive for pumps?

• Electric motor, human and/or animal

• Gasoline or diesel engine

• Solar and wind

• All of the above

Type of pump that uses the back-and-forth motion of mechanical parts, such as piston or diaphragms, to pressurize the fluid.

• Centrifugal

• Reciprocating

• Axial

• None of the above

Type of pump that uses the centrifugal force imparted to the fluid by one or more rotating elements called impellers to increase the kinetic energy and the pressure energy of the fluid.

• Centrifugal

• Reciprocating

• Axial

• None of the above

Type of pump that develops most of the suction and of the discharge head by propelling or by the lifting action of the impeller vanes in the water.

• Centrifugal

• Mixed-flow

• Axial-flow

• None of the above

Type of pump that uses gears, vanes, lobe or screw to trap and to convey the fluid from the inlet to the outlet of the pump.

• Centrifugal

• Reciprocating

• Rotary

• None of the above

Type of pump with impellers rotating inside a closed casing which draws water into the pump through a central inlet opening and forces water out through a discharge outlet at the periphery of the housing by centrifugal force.

• Diffuser pump

• Centrifugal pump

• Volute pump

• None of the above

Type of centrifugal pump in which its impeller is surrounded by a set of vanes.

• Diffuser pump

• Centrifugal pump

• Volute pump

• None of the above

Diffuser vanes have ____ near the impeller and are gradually enlarged toward their outer diameter where the fluid flows into the chamber and around the pump discharge.

• big openings

• medium-size openings

• small openings

• None of the above

Type of a centrifugal pump with spiral-curve casing.

• Diffuser pump

• Volute pump

• Self-priming pump

• None of the above
