At 400 psi, the pump yawned. At 800, it began to sing—a low, resonant hum that vibrated up through Leo’s boots. By the time the needle kissed 1,150 psi, the shop had gone quiet. Even the forklift driver killed his engine.
Leo forced a laugh. He clamped the hydrostatic test unit to the pump’s casing, filled it with dyed-red water, and began to crank the pressure.

(Where $N$ = pump speed, $Q$ = flow rate at best efficiency point).
Leo’s hand hovered over the bleed valve. The spec called for a fifteen-minute hold at 1,200 psi. No drop. No sweat. No visible distortion. At 400 psi, the pump yawned
He gave the final crank.
$$S = \fracN \sqrtQNPSH3^0.75$$
A major focus of ANSI/HI 9.8 is the relationship between the operating flow and the Best Efficiency Point (BEP).
The following key considerations are addressed in ANSI/HI 9.8: Even the forklift driver killed his engine
ANSI/HI 9.8 provides guidelines for designing and evaluating pump intakes to ensure reliable and efficient pump operation. By following the design guidelines, procedure, and best practices outlined in this guide, engineers and designers can optimize pump intake design and prevent common problems, such as turbulence, vortices, and air entrainment.
