Hydraulic Institute Engineering Data Book =link= Jun 2026

The keyword "Hydraulic Institute Engineering Data Book" now also refers to digital access.

The Hydraulic Institute is currently integrating the Data Book into the , a cloud-based platform. Future editions will likely feature:

Loss coefficients for elbows, tees, and reducers.

Because the Hydraulic Institute is an ANSI-accredited standards developer, the data book serves as a legally and commercially recognized authority in contractual disputes or engineering specifications. hydraulic institute engineering data book

Identifying causes of low flow, vibration, or cavitation.

A crude oil pipeline is designed for 140°F (low viscosity). At startup, the oil is 60°F (high viscosity). Section E (Viscous Correction) provides factor charts. The engineer inputs the cold viscosity, finds that friction loss is 4x higher, and specifies a VFD (Variable Frequency Drive) for slow ramp-up, preventing motor overload and cavitation.

One of the most frequently used sections is the compilation of friction loss tables for standard steel pipes, PVC, and other pipe materials. Engineers use these tables to estimate head loss due to pipe friction ( The keyword "Hydraulic Institute Engineering Data Book" now

Published by the itself—an organization founded in 1917 and now recognized for developing over thirty ANSI/HI pump standards—this book has served for more than 50 years as the starting point for generations of engineers seeking to understand and solve problems related to fluid transfer. It serves as a vital companion to the more formal and exhaustive HI Standards, offering practical, ready-to-use information that facilitates day-to-day engineering tasks.

Beyond the fluid itself, the book aids in the selection process.

Specific coefficients for materials ranging from ductile iron and carbon steel to modern PVC and fiberglass. At startup, the oil is 60°F (high viscosity)

It is important to distinguish the Engineering Data Book from the ANSI/HI Standards (such as HI 1.1-1.6 for Centrifugal Pumps).

For professionals tasked with designing, specifying, operating, or maintaining pumping systems, this publication is far more than a manual. It is the industry’s codified wisdom. This article provides a deep dive into what the Hydraulic Institute (HI) Engineering Data Book is, why it is indispensable, what specific data it contains, and how to leverage it for optimal system performance.

In the world of fluid motion, precision is not just a metric; it is a language. For over a century, the Hydraulic Institute (HI) has served as the authoritative voice for pump and pumping systems. While the Institute is famous for its ANSI/HI standards, there is one specific publication that acts as the silent workhorse for design engineers, field technicians, and consulting firms:

. Accurate calculations prevent cavitation, which destroys impellers and seals. 3. Energy Efficiency Optimization
