The Hydraulic Institute (HI) Engineering Data Book is a comprehensive technical reference for the pump industry, offering essential data on fluid characteristics, pipe friction loss, and calculations. The content, originally published in1979 and updated in 1990, has been modernized into the free, interactive HI Data Tool which includes calculators for piping and system performance.

For those serious about the art and science of pumping, the HI Data Book is not an option—it is a necessity. hydraulic institute engineering data book
The Data Book does not simply list the formulas; it provides pre-calculated loss tables for various pipe materials (steel, PVC, HDPE, concrete). It accounts for aging factors (C-values over time), which is critical for retrofitting old systems. The Hydraulic Institute (HI) Engineering Data Book is
Final Call to Action: Visit pumps.org to verify the latest edition number (currently aligning with the HI Pump & System Standards 2023-2024 updates). Ensure your team is working from the current data, not a 15-year-old "Orange Book" that lacks modern slurry and high-temperature data. Engineering Data Library - Pumps
Historically, the Engineering Data Book was a spiral-bound volume of charts, nomographs, and tables. Engineers manually plotted curves on graph paper.
