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

Flow measuring devices exhibit increasing head loss in the following sequence:

1. Flow nozzle: Generates the lowest head loss, attributed to its streamlined design.
2. Venturimeter: Experiences slightly greater head loss than a flow nozzle, yet maintains efficiency.
3. Orifice meter: Induces the most substantial head loss, resulting from abrupt flow direction changes and a significant pressure drop.
