# MCQs on Pipe Network

1 - Question

What is the aim of pipe network analysis?
a) To determine the mass of fluid
b) To determine the volume of fluid
c) To determine the flow rates and pressure drops
d) To determine the cross sections of the pipe

c
Explanation: Pipe analysis is an analysis that is carried out in various aspects. It mainly concentrates on the fluid through a hydraulics network. Hydraulic networks are networks that contain several interconnected branches. The aim is to determine pressure drops and fluid flow rates.

2 - Question

The steady- state flow must satisfy ___________
a) Kirchhoff’s law
b) Newtons law
c) Rutherford’s experiment
d) Kepler’s law

a
Explanation: The steady state flow must satisfy Kirchhoff’s first and second law. First law states that the total flow into the junction equals the total flow away from the junction. Second law is called the law of conservation of mass. It states that between two junctions, the head loss is independent of the path followed.

3 - Question

What are the assumptions made for a fluid flow through a pipe?
a) Fluid inertia is not taken
b) Viscosity is not taken
c) Volume is not considered
d) Mass is not considered

a
Explanation: During a fluid flow through a pipe, there are various design considerations. But, the two major assumptions are that the flow is assumed to be fully developed. Also, fluid inertia is not taken into account.

4 - Question

Which among the following is not global parameters of fluid?
a) Viscosity
b) External diameter
c) Density
d) Mass flow rate

b
Explanation: External diameter is not a global parameter. It is one of the most essential pipelining parameters. It helps in determining the type of pipe and material to be used for the same.

5 - Question

What is the default value of pipe length?
a) 5 meters
b) 20 meters
c) 10 meters
d) 30 meters

a
Explanation: Pipe analysis is carried out in various aspects. It mainly concentrates on the fluid through a hydraulics network. After the analysis, they have determined the default length of the pipe as 5 meters.

6 - Question

What is the best suitable type of pipe?
a) Hard
b) Rigid
c) Tough
d) Malleable

b
Explanation: The best suitable parameter to determine the pipe is either rigidity or flexibility. If we set it with rigidity, the compliance of the walls are not taken into account. Flexibility is preferred for metal pipes and hoses.

7 - Question

What is the default value of specific heat ratio in pipelines?
a) 1
b) 1.2
c) 1.4
d) 2

c
Explanation: Pipe analysis is carried out in various aspects. It mainly concentrates on the fluid through a hydraulics network. Specific heat ratio is the ratio of heat to the constant volume chamber block. It has got a default value of 1.4.

8 - Question

Where is the surge tank located in a hydroelectric power plant?
a) Dam
