Water is the standard against which most pumps are rated. The book provides exhaustive tables for the physical properties of water across a wide temperature range.
Originating as a 1921 industry pamphlet, the Hydraulic Institute’s Engineering Data Book evolved over a century from essential printed friction tables into a modern digital platform for pump engineers. The resource transitioned to a free, interactive "Engineering Data Library" in 2020, offering real-time calculators for system efficiency.

HI revises the Data Book periodically. Significant updates occur when new research on viscosity effects, slurry transport, or pump efficiency testing is validated. As of the latest edition (the 4th or 5th, depending on revision cycle), content on VFDs, energy cost analysis, and pump system optimization has been greatly expanded.
