: Detailed data on physical properties like viscosity (absolute and kinematic), specific gravity, and vapor pressure for various liquids. Fluid Flow & Friction

: Comprehensive charts on friction factors and head loss calculations for pipes, fittings, and valves. Piping Materials

Hydraulic Institute (HI) Engineering Data Book is a cornerstone reference for pump and system engineers, providing essential technical data on fluid characteristics, flow, and piping materials. While originally published in print, much of its content has been transitioned to the interactive HI Engineering Data Library to support modern digital workflows. Core Technical Content

: Extensive conversion tables, tank data, and sample calculations for pump and system principles. System Design Concepts

: This is the most widely recognized print version, known for its fold-out pages of friction factor charts. Digital Access : Official copies are available as Secure PDFs or through the Pumps.org web store HI Engineering Data Library (EDL)

: Guidance on complex topics such as Net Positive Suction Head (NPSH), pump and system curves, and viscosity corrections. Publication Formats & Access Second Edition
