Question:-
In a two-dimensional flow in x-y plane if (u/y)= (v/x), then the fluid element will undergo
Option (A)
Translation only
Option (B)
Translation and rotation
Option(C)
Translation and deformation
Option(D)
Rotation and deformation
Correct Option:
(A)
Question Solution:
Irrotational flow:- If the fluid particle don’t rotate about their mass center while moving in the direction of motion, the flow is called as irrotational flow. (tree vortex)
w = (1/2)[( v/x)-( u/y)] = 0
\ (v/x)=( u/y)
