MCQs on Fluid Flow Methods and Types
1 - Question
In which method of fluid flow analysis do we describe the motion parameters at a point?
a) Langragian method
b) Eulerian Method
c) Control volume analysis
d) None of the mentioned
View Answer
b
Explanation: In Eulerian method,we describe velocity, acceleration pressure etc at a point in flow field.
2 - Question
Which method is most commonly used in fluid mechanics for analysis?
a) Langragian method
b) Eulerian Method
c) Control volume analysis
d) None of the mentioned
View Answer
b
Explanation: In Eulerian method,we describe velocity, acceleration pressure etc at a point in flow field.hence, it is also most commonly used in fluid mechanics.
3 - Question
.In unsteady flow, the flow parameters change with respect to position.
a) True
b) False
View Answer
b
Explanation: In unsteady flow, the flow parameters change with respect to time.
4 - Question
Uniform flow is defined as the type of flow in which acceleration is zero i.e velocity is constant.
a) True
b) False
View Answer
b
Explanation: Uniform flow is defined as the type of flow in which the velocity does not change with respect to space. It can change with respect to time.
5 - Question
In laminar flow fluid particles flow along a streamline.
a) True
b) False
View Answer
a
Explanation: As per the definition of laminar flow, fluid particles flow in a streamlined manner.
6 - Question
Eddies formed in the turbulent flow are major cause of the energy loss in the turbulent flow.
a) True
b) False
View Answer
a
Explanation: Due to zig zag motion of particles eddies are formed and they lead to energy losses.
7 - Question
For compressible flow specific gravity remains same.
a) True
b) False
View Answer
b
Explanation: For compressible flow, density changes and therefore specific gravity changes.
8 - Question

a) Turbulent flow
b) Irrotational flow
c) Rotational flow
d) None of the mentioned
View Answer
d
Explanation: It is random manner of fluid flow.
9 - Question
If the velocity is function of two space coordinates along with time then fluid flow is three dimensional in nature.
a) True
b) False
View Answer
a
Explanation: If the velocity is function of three space coordinates along with time then fluid flow is three dimensional in nature.
