Which of the following figures shown below is correct regarding the steady flow of a non viscous liquid ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
By equation of continuity
Av=constant `" "…(i)`
where A is the area of cross-section of tube and v is the velocity of flow.
From (i) it is clear that, when area of cross section of tube is less, the velocity of the liquid flow is more.
So the velocity of liquid flow of a constriction of tube is more than the other portion of tube.
By Bernoulli's theorem `P+(1)/(2)rhov^(2)` =constant.
