(Where $N$ = pump speed, $Q$ = flow rate at best efficiency point).

A needle-thin jet of red water shot out, sizzling as it depressurized. The groan faded. The crack stopped growing. The needle fell—1,100… 900… 400… 0. ansi hi 9.8

is the definitive American National Standard for the design of intakes for rotodynamic pumps. Published by the Hydraulic Institute (HI) , this standard provides engineers and facility owners with normative criteria to ensure that fluid enters a pump in a uniform, steady state, free from excessive swirl or entrained air. Proper adherence to these guidelines is critical for preventing operational issues such as cavitation, vibration, and premature mechanical failure. Scope and Applications (Where $N$ = pump speed, $Q$ = flow
