Which of the following conditions given below is a case of forced vortex flow.
i. Flow of liquid inside the impeller of centrifugal pump. ii. Flow of liquid around a circular bend in pipe. iii. Flow of liquid through the runner of turbine. iv. A whirlpool in a river.
Question 2
Assertion: The flow of fluid is said to be steady if at any given point, the velocity of each passing fluid particle remains constant. Reason: The path taken by a fluid particle under a steady flow is a streamline.
Question 3
Consider following statement:
1) Streamlines can never cross each other.
2) Spacing of streamlines varies inversely with velocity at that section.
3) Locus of all particles passed through a fixed point at any instant is known as path line.
4) For a uniform flow, streamline, path line and streak line coincide with each other.
Correct statement(s) is/are :
Question 4
Statement (I): Fluid motion is irrotational if and any if velocity potential function exists.
Statement (II): For velocity potential function (ϕ), gradϕ= 0
Question 5
Which one of the following is the use of flow net analysis in fluid mechanics?
Question 6

Question 8
Consider the following statements : 1) There is no flow across a streamline. 2) Streamline spacing varies directly with velocity at the section. 3) Streamlines do not cross. 4) In steady flow, streamline pattern does not change with time. Which of these statements in respect of stream flow pattern are correct?
Question 9
A streamlined body is one for which the
Question 10
