Hydraulic Institute Engineering Data Book Jun 2026

Detailed methodologies and tables for calculating friction losses in pipes, fittings, and nozzles. This includes specialized data for water friction loss, friction loss of paper stock, and analytical approaches to slurries.

Standard pump performance curves are generated using water. When pumping viscous fluids, head, flow, and efficiency drop. This chapter uses the of correction factors for centrifugal pumps handling viscous fluids—a method that is universally accepted in industry. hydraulic institute engineering data book

For more than 50 years, the has served as an essential technical reference for professionals in the pumping and fluid handling industries. Published by the Hydraulic Institute (HI), the global authority on pumps and pumping systems, this book provides a comprehensive "wealth of information" for solving complex problems related to fluid transfer, piping system design, and pump selection. Core Technical Content When pumping viscous fluids, head, flow, and efficiency drop

In the complex world of fluid dynamics and industrial pumping systems, precision is not a luxury; it is a necessity. A miscalculation in pipe friction, a misunderstanding of fluid viscosity, or an error in pump sizing can lead to catastrophic system failures, exorbitant energy costs, and reduced equipment lifespan. For decades, engineers, designers, and plant operators have turned to a singular, authoritative source to mitigate these risks: the . Published by the Hydraulic Institute (HI), the global

Before the standardization provided by HI, the industry was fragmented. Manufacturers used different testing methods and rating systems, making it difficult for engineers to compare pumps across brands. The HI standards brought order to chaos. The Engineering Data Book acts as the technical compendium to these standards. While the HI Standards define how to test and rate a pump, the Data Book provides the foundational engineering formulas, fluid properties, and pipe flow data required to understand how the pump will interact with the system.

The HI Data Book provides extensive Darcy-Weisbach friction factor tables. While textbooks show the Moody Chart pictorially, the HI book provides tabulated values for specific pipe diameters, materials (steel, PVC, HDPE, copper), and flow regimes.

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.
