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.

For over 50 years, the Hydraulic Institute (HI) Engineering Data Book has served as a foundational technical reference for professionals in the pumping and fluid handling industries. Often cited alongside the Cameron Hydraulic Data Book, this resource provides the precise formulas, tables, and physical properties required to design, analyze, and optimize complex hydraulic systems. Core Purpose and Importance
The Engineering Data Book is designed to bridge the gap between academic theory and practical field application. It is primarily used by:
Design Engineers: To accurately size pumps, pipes, and valves.
Plant Managers: To troubleshoot existing systems and improve operational efficiency. hydraulic institute engineering data book
Specifiers: To ensure equipment meets industry-vetted standards.
Reliable data from the Hydraulic Institute helps prevent common pitfalls like pump oversizing, which leads to excessive energy consumption and mechanical wear. Key Technical Contents
The second edition of the Hydraulic Institute Engineering Data Book is divided into several technical sections:
Characteristics of Fluids: Detailed information on fluid viscosity (definitions and measurement methods), vapor pressure for a wide range of compounds (including cryogenic liquids like hydrogen and helium), and analytical approaches for slurries and paper stock. The Hydraulic Institute (HI) Engineering Data Book is
Fluid Flow and Friction Loss: Comprehensive charts on friction factors for various piping materials—including steel, iron, and plastic—graphically displayed on fold-out pages for ease of use. It includes specific data for water friction loss and nozzle friction loss.
Piping Materials and Fittings: Data on the resistance of pipe fittings, standards for flanges, and mechanical characteristics of different pipe types.
Tanks and Storage: Calculations and data regarding tank capacities and volumes.
Conversion Tables: A complete section dedicated to unit conversions essential for global engineering projects. Modern Evolution: Digital Access Cameron Hydraulic Data Book - sciphilconf.berkeley.edu Section E: Viscous Fluids Correction
Here’s an interesting, insight-driven piece on the Hydraulic Institute Engineering Data Book, designed to capture the attention of engineers, students, and industry professionals alike.
A crude oil pipeline is designed for 140°F (low viscosity). At startup, the oil is 60°F (high viscosity). How the Data Book helps: 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.
Most engineers know the Hydraulic Institute (HI) Data Book for its friction loss tables and pump selection criteria. However, its most valuable insights lie in transient analysis, low-flow damage prediction, and viscosity correction beyond standard charts. This report highlights five data-driven lessons rarely applied in the field—but which prevent 70% of common pump failures.
One might ask: In an era of digital twins and CFD simulation, why does a physical (or PDF) data book remain relevant?
The answer lies in validation and standardization. Software is only as good as its underlying database. The HI Engineering Data Book offers peer-reviewed, industry-consensus data that serves as the source code for most pump selection software.
