What is the primary purpose of a pump?

• To compress gases into a liquid

• To increase the temperature of a fluid

• To transfer fluid from one point to another

• To filter impurities from a liquid

Which type of pump is ideal for high-flow, low-viscosity fluids?

• Reciprocating Pump

• Positive Displacement Pump

• Diaphragm Pump

• Centrifugal Pump

What does the term 'head' refer to in pump operation?

• The speed of the fluid flow

• The height to which a pump can raise a fluid

• The pressure exerted by the pump

• The temperature of the fluid

What is cavitation in the context of pumps?

• The process of filtering liquids

• The increase of pressure in a fluid

• The measurement of fluid velocity

• The formation and collapse of vapor bubbles in a liquid

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

• They operate based on kinetic energy

• They are not suitable for high-viscosity fluids

• They are only used for low-viscosity fluids

• They continuously add energy to the fluid

What does NPSH stand for in pump terminology?

What is the effect of increasing the impeller diameter in a pump?

• Decreases the flow rate

• Increases the efficiency

• Increases the capacity

• Reduces the head

Which type of pump is best suited for handling corrosive fluids?

• Positive Displacement Pump
