A real question from the CFD Basic Apparatus and Hydraulics Practice Test bank. Answer it, see the explanation, then decide.

Multiple Choice

The discharge pressure of a centrifugal pump is influenced by the speed of the impeller.

Explanation:
Increasing the impeller speed adds more energy to the fluid, which raises the head the pump can develop. For a centrifugal pump with fixed geometry, the head is proportional to the square of the speed (H ∝ N^2). Since discharge pressure is tied to the head by P_discharge ≈ ρ g H, spinning the impeller faster increases the discharge pressure. The actual pressure at the discharge also depends on the system’s resistance, so the operating point may shift, but the capability to generate higher pressure grows with speed. Temperature isn’t the controlling factor here, and there’s enough information to connect speed to pressure via the head relation.

    Decent resource, but I found some questions a bit niche and not aligned with what I saw on test day. Still, the explanations were helpful, and the randomized approach keeps you from guessing patterns. With more practice on weak areas, this could be a solid 4 or 5.
