Hydraulic Institute Engineering Data Book

The Hydraulic Institute (HI) Engineering Data Book is a long-standing, comprehensive technical resource for fluid characteristics, piping, and friction loss calculations, widely used by pump professionals. It has evolved into a digital, interactive solution known as the HI Data Tool, which offers online calculators, visualizers, and updated technical data.

How the Data Book helps:

A plant replaces a pump for a 100°F water loop. The new pump produces 500 GPM at 100 ft head, but the system only needs 400 GPM. The operator throttles a valve, wasting energy. Section B provides the K-factor for a partially open gate valve. Section C teaches the engineer how to trim the pump impeller using the affinity laws (Flow ∝ Diameter; Head ∝ Diameter²), saving $12,000/year in energy.
