Question 21 of 30
Select the correct statement regarding pressure.
Pressure type vacuum valves can prevent Backflow.
Dynamic pressure is a function of the fluid velocity and its density.
The water reservoir of a self-priming pump may be at the back of the impeller.
Stripping pumps are not of the self-priming type. **Correct answer : Dynamic pressure is a function of the fluid velocity and its density.**

Answer & Explanation
The correct answer is Option B: Dynamic pressure is a function of the fluid velocity and its density..
Bernoulli's principle establishes that dynamic pressure is directly related to the density of the fluid and the square of its velocity. This relationship is fundamental to understanding pump head, flow velocity, and pressure energy conversion within the pump casing.
