Flow rate through an orifice is _____________ the pressure differential?
Correct answer: C. Proportional to the square root of
- A. Proportional to
- B. Inversely proportional to the square root of
- C. Proportional to the square root of
- D. Inversely proportional to the square of
Explanation
For an orifice, the pressure drop is converted into velocity through Bernoulli's relation, giving Q proportional to √ΔP when the other properties and the orifice area are fixed. Thus flow is proportional to the square root of the pressure differential, not to the differential itself.
