Hydraulic Institute Engineering Data Book

Most software handles clean water beautifully. But what about:

The Data Book dedicates serious real estate to non-Newtonian fluids, slurries, and two-phase flow — the messy, real-world stuff that breaks pumps if you get it wrong.

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. hydraulic institute engineering data book

Field experience repeatedly shows that the root cause of pump failure is not mechanical defect but incorrect application. Pumps run dry, cavitate, operate far from best efficiency point (BEP), or suffer from chronic motor overload. The HI Engineering Data Book equips professionals to ask and answer: What is my system curve? What is my NPSH available? How will viscosity change my head and flow?

In an era of energy consciousness, the Data Book also delivers a strong return on investment. A single energy optimization project—such as trimming an impeller or adjusting a VFD—inspired by a calculation in the Data Book can save thousands of dollars annually in electricity costs, often paying for the book a hundred times over. Most software handles clean water beautifully

Contrary to a standard textbook, the Hydraulic Institute Engineering Data Book is a curated collection of empirical data, formulas, conversion factors, and physical properties specifically tailored for pump system engineers.

The keyword "Hydraulic Institute Engineering Data Book" now also refers to digital access. The Data Book dedicates serious real estate to

The tables of K-factors often contain superscripts. A footnote might state: "Values assume fully turbulent flow (Re > 10^5). For low Re, multiply by correction factor 1.2." Missing these footnotes leads to 20% design errors.

A pump cannot be selected in isolation; it must match the system it serves. The Data Book dedicates significant space to calculating system resistance.
