The is a cornerstone resource for engineers, designers, and maintenance professionals involved in the design, selection, and operation of pumping systems. For decades, it has served as the "go-to" reference for reliable, technical information on fluid dynamics and pump performance, now modernized into the web-based Engineering Data Library (EDL).

In the age of automated modeling software, you might wonder if a "data book" is still relevant. The answer is yes, for three main reasons: hydraulic institute engineering data book

= Friction factor (derived from the Colebrook equation or Moody diagram) = Length of the pipe = Inside diameter of the pipe = Average fluid velocity = Acceleration due to gravity Net Positive Suction Head (NPSH)

Originating as a 1921 industry pamphlet, the Hydraulic Institute’s Engineering Data Book evolved over a century from essential printed friction tables into a modern digital platform for pump engineers. The resource transitioned to a free, interactive "Engineering Data Library" in 2020, offering real-time calculators for system efficiency. Read the full history at Pumps & Systems .

While modern Computational Fluid Dynamics (CFD) software and computer-aided piping programs dominate the industry, the Hydraulic Institute Engineering Data Book remains an essential resource. It serves as the primary verification baseline for modern software algorithms. Software programs can produce errors if the underlying assumptions or inputs are incorrect; engineers use the data book to perform manual "sanity checks" on critical calculations. Furthermore, its standardized tables eliminate regional and manufacturer biases, providing a universally accepted metric for legal compliance, safety reviews, and contract bidding specifications.

The data is validated by experts within the Hydraulic Institute, the recognized authority on pump standards.

To ensure equipment meets industry-vetted standards. The answer is yes, for three main reasons:

This is the most dog-eared section in any engineer’s office.

Guidelines for calculating increased roughness in older piping. 3. Valves and Fittings Pressure Drops

The Data Book established a uniform methodology based on empirical testing and fluid dynamic theory. It ensures that when an engineer calculates the head generated by a pump or the friction loss in a pipe, the result is consistent regardless of the manufacturer. It is often referenced in legal contracts and engineering specifications as the default standard for dispute resolution.

Calculations that account for how internal corrosion and scaling increase friction over 10, 20, or 30 years.

The foundation of hydraulic calculation lies in understanding the fluid being pumped. The Data Book provides extensive tables for:
