Hydraulic Institute Engineering Data Book May 2026

The Hydraulic Institute Engineering Data Book is not merely a collection of formulas; it is a living standard validated by decades of pump system performance audits. The engineer who replaces generic assumptions with HI's empirical data will achieve three things: higher reliability, lower lifecycle costs, and a system that performs on day one as it will on day 3,000.

Solution: Consulting the HI Engineering Data Book, Table 8.4 (Hazen-Williams $C$ Factors for Industrial Service), the engineer noted that for carbon steel carrying condensate with trace CO2, the sustained $C$ factor is actually . hydraulic institute engineering data book

Outcome: By recalculating the system curve using the HI-sustained $C$ value, the engineer correctly sized a new impeller trim. The pump was restored to its BEP, reducing vibration by $22%$ and saving $$18,000$ annually in electricity. The Hydraulic Institute Engineering Data Book is not
