, when the Hydraulic Institute was founded as the premier association for pump manufacturers in North America. Early engineers faced a chaotic landscape of conflicting terms and unpredictable calculations until the Institute began standardizing definitions for everyday pump work.
For a young engineer, working through problems using the HI Data Book builds intuition that no software can provide. For a senior engineer, it is a trusted second opinion. For a plant manager, it is the risk mitigation tool that ensures the next pump purchase will not fail. hydraulic institute engineering data book
The Engineering Data Book is the practical manifestation of this century of expertise. While HI publishes numerous standards (e.g., ANSI/HI 14.1 for rotodynamic pumps), the Engineering Data Book is the comprehensive handbook that provides the underlying physical constants, empirical formulas, and conversion factors needed to apply those standards effectively. , when the Hydraulic Institute was founded as
This article provides a deep dive into the Hydraulic Institute (HI), the structure and content of the Engineering Data Book, its key applications in the field, and why it remains the gold standard, even in an era of digital calculators and simulation software. For a senior engineer, it is a trusted second opinion
Every pump calculation begins with the fluid. The Data Book provides extensive tables for the properties of water, the most common pumped fluid, across various temperatures. This includes data on specific gravity, viscosity, and vapor pressure.
