Hydraulic Institute Engineering Data Book High Quality Jun 2026

The is not a "nice to have"—it is a pillar of professional practice. In an era where "Google engineering" often leads to the use of generic online calculators, the HI Data Book provides auditable, defensible, and peer-reviewed data.

Friction is the enemy of efficiency in fluid systems. As liquid rubs against the interior walls of a pipe, energy is lost. The HI Engineering Data Book provides massive, highly detailed tables detailing friction losses based on:

The Hydraulic Institute Engineering Data Book remains an indispensable resource in mechanical and chemical engineering. It consolidates complex fluid dynamics into accessible charts and formulas, facilitating the accurate selection of rotating equipment. While technology has shifted from nomographs to algorithms, the fundamental principles contained within the book—affinity laws, system resistance, and viscosity corrections—remain the bedrock of hydraulic system design. For any engineer tasked with moving fluids, the Data Book represents the highest standard of technical accuracy and reliability. hydraulic institute engineering data book

Field experience repeatedly shows that the root cause of pump failure is not mechanical defect but incorrect application. Pumps run dry, cavitate, operate far from best efficiency point (BEP), or suffer from chronic motor overload. The HI Engineering Data Book equips professionals to ask and answer: What is my system curve? What is my NPSH available? How will viscosity change my head and flow? The is not a "nice to have"—it is

: While the book is still available in print (notably the 2nd Edition from 1990), the digital tool provides a free, frequently updated alternative for modern engineering workflows. Key Editions

The serves as the companion volume to those standards. While the standards tell you how to test a pump or how to calculate Net Positive Suction Head (NPSH), the Data Book provides the raw material —the fluid properties, friction loss coefficients, and mathematical constants—needed to perform those calculations.
