The foundation of hydraulic calculation lies in understanding the fluid being pumped. The Data Book provides extensive tables for:
One might ask: In an era of digital twins and CFD simulation, why does a physical (or PDF) data book remain relevant?
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.
= Friction factor (derived from the Colebrook equation or Moody diagram) = Length of the pipe = Inside diameter of the pipe = Average fluid velocity = Acceleration due to gravity Net Positive Suction Head (NPSH) hydraulic institute engineering data book
You need to certify a pump's efficiency for an energy rebate program. The Solution: The Data Book contains the appendices to HI Standard 40.6 (Methods for Rotodynamic Pump Efficiency Prediction). You look up the specific speed and flow rate to find the "allowable losses" for bearings and seals. This allows you to accurately calculate the pump efficiency (hydraulic power divided by shaft power) without destroying the pump for internal inspection.
Are you trying to , select a pump , or troubleshoot a system issue ? Do you need help calculating friction loss or NPSH ?
The Hydraulic Institute Engineering Data Book is a specialized reference manual designed for engineers, designers, and operators of fluid handling systems. Unlike general fluid mechanics textbooks, it focuses heavily on practical, empirical data and standardized formulas validated by industry experts. Core Objectives The book provides exhaustive tables for the physical
Visual aids and tables to quickly identify laminar, transitional, or turbulent flow regimes. 3. Valves, Fittings, and Compressible Flow
In the complex world of fluid dynamics and rotating equipment, precision is not a luxury; it is a necessity. For decades, the Hydraulic Institute (HI) has served as the authoritative voice for the pump industry in North America and beyond. While HI is famous for its pump standards (ANSI/HI Standards), its Engineering Data Book remains one of the most practical and widely utilized resources in the engineer’s toolkit.
The data is peer-reviewed and updated by leading experts in pump manufacturing and fluid piping systems. Summary of Essential Formulas Found in the Book Formula Type Key Variables Required from Book Darcy-Weisbach Calculates precise head loss due to friction Pipe roughness ( ), Kinematic viscosity ( Reynolds Number Determines laminar vs. turbulent flow regimes Fluid velocity ( ), Inside pipe diameter ( ), Viscosity ( Resistance Coefficient ( ) Determines velocity and continuity in pipe networks Actual inside pipe dimensions You look up the specific speed and flow
The is more than just a reference book; it is an essential engineering tool. By providing accurate, industry-vetted data, it empowers engineers to design, install, and operate pumping systems that are efficient, reliable, and durable.
For over 50 years, the 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
Whether you are designing a simple municipal water loop or a complex refinery piping system, the Hydraulic Institute Engineering Data Book provides the mathematical framework necessary to ensure your hydraulic systems run safely, efficiently, and reliably.
