Pressure must increase in the divergent portion of venturimeter as the velocity of flow decrease.

Sagar dudhal said:   9 years ago
Yes, as area increases velocity decreases and pressure should increase.

Sidhant singh said:   9 years ago
Why should decrease?

We know that area increase velocity decrease and pressure increase.

Abin said:   9 years ago
Pressure = force / area.

Through convergent section : kinetic energy will increase and presser energy will decrease.

Through Divergent section : kinetic energy will decrease and pressure energy will increase.

Yes, the answer should be B according to Bernoulli's equation.

Akshay patil said:   8 years ago
The Correct answer is C decrease because P=F/A so as area increase pressure decrease.

The velocity reaches its maximum value and pressure reaches its minimum value at the throat. Subsequently, a decrease in the velocity and an increase in the pressure takes place in course of flow through the divergent part.
