Which of the following figure shown below is correct regarding the steady flow of a non viscous liquid?
A
B
C
D
Answer
Explanation
Solution
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 construction of tube is more than the other portion of tube.
By Bernoulli’s theorem 
Therefore if v is more, P is less and vice versa.
