Venturimeter: velocity at the throat versus at the inlet In a venturimeter working under full-bore flow, compare the fluid velocity at the throat with the velocity at the inlet. Choose the correct relation.

Q: Venturimeter: velocity at the throat versus at the inlet In a venturimeter working under full-bore flow, compare the fluid velocity at the throat with the velocity at the inlet. Choose the correct relation.

Concept/Approach From continuity, Q = A V = constant. Because the throat area is smaller than the inlet area, the velocity must increase at the throat to maintain the same discharge. Final Answer Velocity at the throat is greater than at the inlet

Difficulty: Easy

Velocity at the throat is greater than at the inlet
Velocity at the throat is lower than at the inlet
Velocity at the throat equals the inlet velocity
Cannot be compared without density data

Correct Answer: Velocity at the throat is greater than at the inlet

Explanation:

Concept/Approach
From continuity, Q = A V = constant. Because the throat area is smaller than the inlet area, the velocity must increase at the throat to maintain the same discharge.

Final Answer
Velocity at the throat is greater than at the inlet
