Hydraulic Institute Engineering Data Book
: Features interactive system curves, variable-speed pump curves, and parallel pump curves to help users visualize system behavior.
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.
What many don’t realize: the is not static. The HI updates it every few years, adding new sections on:
Pumps don’t just move water. They move syrups, oils, chemicals, and slurries. The Data Book provides extensive tables on the physical properties of various liquids. Crucially, it includes charts for . Since most pump performance curves are based on water, the HI data allows you to accurately predict how a pump will perform when handling thicker fluids. 2. Friction Loss Calculations hydraulic institute engineering data book
Designing an efficient pumping system requires calculating the total dynamic head (TDH). Engineers use the pipe friction data to plot system head curves against pump performance curves. This ensures the selected pump operates near its best efficiency point (BEP). 2. Net Positive Suction Head (NPSH) Analysis
Before diving into the specifics of the data book, it is important to understand the stature of its publisher. Founded in 1917, the Hydraulic Institute is the largest association of pump manufacturers in North America. As an ANSI-accredited standards developing organization, HI is the global authority on pumps and pumping systems. The Institute publishes numerous standards covering everything from pump nomenclature and design to installation, operation, and performance testing.
The Industry Bible: Unlocking the Power of the Hydraulic Institute Engineering Data Book While technology has shifted from nomographs to algorithms,
The HI Engineering Data Book is highly recommended for:
Detailed and relative roughness factors for new clean pipes. Piping and Infrastructure :
In the modern era, the data within the book has been digitized: The HI updates it every few years, adding
When a project is out for bid, referencing "HI Standards" or "HI Data" provides a legal and professional baseline that all contractors and manufacturers recognize.
A standout feature of the Data Book is its exhaustive treatment of head loss:
While the complete table of contents for the current edition is not publicly listed in full, descriptions of the book and its second edition reveal a comprehensive structure centered on three main pillars: , Fluid Flow , and Characteristics of Piping Materials . Within these sections, the book provides a wealth of specific technical data:
The book utilizes the Darcy-Weisbach equation and provides extensive friction loss tables for pipes of various materials (steel, cast iron, plastic) and diameters.
