Hydraulic Institute Engineering Data Book
The Data Book provides the definitive exposition of the Affinity Laws, which govern the relationship between speed, impeller diameter, flow, head, and power.
The Data Book serves as a materials selector, detailing the characteristics of common piping materials. This allows engineers to assess the suitability of different pipe types based on the fluid being handled and the system's operating conditions.
Cavitation destroys pump impellers and causes catastrophic system failures. Engineers use the vapor pressure data and suction line friction tables from the HI Data Book to calculate . Ensuring NPSHA exceeds the pump’s required NPSH (NPSHR) is critical for system reliability. Energy Efficiency Audits
When operational pumps fail to meet target flow rates, technicians use HI data to check for clogged lines, unexpected throttling, or incorrect system head calculations. Why Engineers Rely on This Reference Accuracy and Standardization hydraulic institute engineering data book
Acquiring the Data Book is an investment in reliable information, but potential buyers should be aware of a few points. Some online reviews note that, for certain users, the book's content is presented in a highly condensed, abstract manner. Others have expressed disappointment with the conclusions drawn from presented data or found the theoretical derivations to be error-prone. It is important to recognize that this is a reference data book, not a theoretical textbook. Its primary strength lies in providing tabulated data, conversion factors, and calculation methods, not in exhaustive theoretical explanations. User expectations should align with its purpose as a practical guide, and having a foundational knowledge of engineering principles is beneficial for effective use.
) to prevent cavitation, which destroys internal components. Diagnosing System Failures
Few topics in pump engineering generate more heated arguments than how much NPSH margin is enough. The Data Book provides a famous table: recommended margins based on service, fluid type, and risk tolerance. It doesn’t end the debate — but it gives you a defensible, industry-backed starting point. That’s gold in a lawsuit or after a catastrophic cavitation failure. The Data Book provides the definitive exposition of
To size pumps, pipes, control valves, and storage vessels during the engineering phase.
The book also includes several appendices with useful data, such as:
In the complex world of fluid dynamics and rotating equipment, precision is not a luxury; it is a necessity. For decades, the Hydraulic Institute (HI) has served as the authoritative voice for the pump industry in North America and beyond. While HI is famous for its pump standards (ANSI/HI Standards), its Engineering Data Book remains one of the most practical and widely utilized resources in the engineer’s toolkit. Energy Efficiency Audits When operational pumps fail to
