: The Hydraulic Institute Engineering Data Book – 2nd Edition is available directly from the Hydraulic Institute Store for $95.00.
While HI standards (such as ANSI/HI) focus on the design and testing of specific pump types, the Engineering Data Book offers the "glue" that binds them together: the data on fluids, pipes, and hydraulics that dictates how a pump performs in the real world. Key Components of the 2nd Edition It eliminates the need to cross-reference multiple generic
Accurate system modeling requires precise fluid data. The manual provides metrics for water, viscous petroleum products, and chemical solutions.
Loss coefficients for elbows, tees, and reducers.
Without question, this is one of the most frequently consulted sections of the Data Book. It contains the primary data needed to calculate friction losses in pipes and fittings. A poor computation of system friction will have a disastrous effect on pump selection, making this section indispensable for accurate system design. Its friction-loss tables are considered a standard industry reference, often cited alongside the Crane Technical Paper . Notably, the book even highlights the potential variation in friction loss for fittings and valves, noting deviations from ±10% to as high as ±50% in certain cases.
