The Correct answer is C decrease because P=F/A so as area increase pressure decrease.

Pushpendra said:   8 years ago
Yes, the answer should be B according to Bernoulli's equation.

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

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

Pressure = force / area.

Why should decrease?

We know that area increase velocity decrease and pressure increase.

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

Sagar Ladkat said:   9 years ago
Pressure must increase in the divergent portion of venturimeter as the velocity of flow decrease.

VAISHALI said:   9 years ago
By continuity equation, the area is inversely proportional to velocity so with the increase in area in the diverging section velocity decreases and therefore by Bernoulli's equation we can conclude that the pressure must increase in this region.

AKKI said:   9 years ago
In divergent, pressure should be increased.

Knowledge said:   9 years ago
Pressure must increases at divergent section.
