# Fluid Mechanics Questions and Answers – Maximum Speed of a Reciprocating Pump

This set of Fluid Mechanics Multiple Choice Questions & Answers (MCQs) focuses on “Maximum Speed of a Reciprocating Pump”.

1. A reciprocating pump is a class of _________
a) Negative displacement
b) Positive displacement
c) Zero displacement
d) Infinite displacement

Explanation: A reciprocating pump consists of a piston pump, plunger and diaphragm pump. It is a class of positive displacement. Reciprocating pumps will last for years and decades.

2. The simplest application of the reciprocating pump is___________
a) Piston pump
b) Plunger
c) Diaphragm pump
d) Bicycle pump

Explanation: Bicycle is the pump is the simplest application of the reciprocating pump. It works on the principle of simple hand operated reciprocating pump. It is used to inflate bicycle tires and various sporting balls.

3. Power operated deep well reciprocating pump is divided into__________
a) Single and double acting
b) Single and multi-stage
c) Piston and plunger
d) Conductive and nonconductive

Explanation: Power operated deep well reciprocating pump is divided into single and double acting. It is classified on the basis of its mechanism. It is distinguished depending on the function of the piston.

4. Which among the following is not an example of a reciprocating pump?
a) Hand pump
b) Wind mill
c) Axial piston pump

Explanation: A reciprocating pump is a class of a positive displacement pump. It includes a piston pump, plunger and a diaphragm pump. It has a long life. Turbine blades are not an example of the reciprocating pump.

5. Pump converts mechanical energy into ________
a) Pressure energy only
b) Kinetic energy only
c) Pressure and kinetic energy
d) Potential energy

Explanation: The main function of the pump is to transfer and convert mechanical energy of a motor into pressure energy and kinetic energy. It plays an important role in the transfer of fluid across the pipeline.

6. Which among the following is not a positive displacement pump?
a) Centrifugal
b) Reciprocating
c) Rotary
d) Ionization pump

Explanation: Centrifugal pumps are not a positive displacement pump. They are a subclass dynamic work absorbing turbo machinery. They are used to transport fluids. It transports fluid by conversion of rotational kinetic energy to hydrodynamic kinetic energy.

7. How do we measure the flow rate of liquid?
a) Coriolis method
c) Conveyor method
d) Ionization method

Explanation: Coriolis concept of measurement of fluid takes place through the rotation with the reference frame. It is an application of the Newton’s Law. The device continuously records, regulates and feeds large volume of bulk materials.

8. Which among the following is called as the velocity pump?
a) Centrifugal
b) Reciprocating
c) Rotary
d) Ionization pump

Explanation: Centrifugal pumps are not a positive displacement pump. They are a subclass dynamic work absorbing turbo machinery. They are used to transport fluids. It transports fluid by conversion of rotational kinetic energy to hydrodynamic kinetic energy.

9. Discharge capacity of a reciprocating pump is lower than that of reciprocating pump.
a) True
b) False

Explanation: Discharge capacity of the reciprocating pump is lower than that of the reciprocating pump. Discharge capacity of fluids is defined as the discharge in terms of the volumetric flow rate. It helps to regulate the flow through a cross sectional area.

10. Which among the following is a high-pressure pump?
a) Centrifugal
b) Reciprocating
c) Rotary
d) Ionization pump

Explanation: Reciprocating pump is the most suitable high-pressure pumps at moderate or low discharges. A reciprocating pump is a class of a positive displacement pump. It includes a piston pump, plunger and a diaphragm pump.
