Understanding Pumps Quiz

What is the primary function of a centrifugal pump?

• To increase the temperature of a fluid

• To increase the pressure of a fluid by converting mechanical energy into hydraulic energy

• To decrease the pressure of a fluid

• To purify the fluid

Which of the following is NOT a type of positive displacement pump?

• Gear pump

• Piston pump

• Diaphragm pump

• Axial flow pump

In a reciprocating pump, what is the component that moves the fluid by a reciprocating motion?

• Impeller

• Piston

• Vane

• Rotor

What principle do hydraulic pumps operate on?

• Bernoulli's principle

• Pascal's law

• Newton's third law

• Archimedes' principle

Which of the following is a characteristic of positive displacement pumps?

• They are most efficient for high flow rates.

• They cannot handle highly viscous fluids.

• They deliver a fixed amount of fluid for each cycle.

• They primarily convert kinetic energy into potential energy.

What is the main advantage of using a centrifugal pump over a positive displacement pump for a given application?

• Higher precision in fluid metering

• Better for high viscosity fluids

• Simpler construction and lower maintenance

• Higher pressure generation

In centrifugal pumps, what transforms the mechanical energy into pressure energy?

• The piston

• The impeller

• The gear

• The diaphragm

Which pump type is best suited for applications requiring high pressure with low flow rates?

• Centrifugal pumps

• Reciprocating pumps

• Axial flow pumps

• Submersible pumps

What is a common use for hydraulic pumps?

• Water filtration

• Power hydraulic systems in machinery

• Increase fluid temperature

• Transporting gases

Which of the following statements is true about the working principle of centrifugal pumps?

• They move fluid by the direct push of pistons.

• They rely on the reciprocating motion of a diaphragm to move fluid.

• They convert rotational kinetic energy to the hydrodynamic energy of the fluid flow.

• They use gears to transport fluid from one side to the other.
