Question

Arrange the following flow measuring devices in the increasing order of head loss caused by them:
(A). Flow nozzle
(B). Venturimeter
(C). Orifice meter

• A. A, B, C
• B. C, A, B
• C. B, C, A
• D. A, C, B

Hint:

Head loss ranking is crucial in selecting flow measuring devices for industrial applica tions.

Answer 1

The Correct Option is A

Head loss in flow measuring devices increases in the following order:

1. Flow nozzle: Causes the least head loss due to its streamlined design.
2. Venturimeter: Has slightly higher head loss than a flow nozzle but remains efficient.
3. Orifice meter: Causes the highest head loss due to abrupt changes in flow direction and a larger pressure drop.
