The Hydraulic Institute has modernized access to the Engineering Data Book.
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.
