Hydraulic Institute Engineering Data Book

The Hydraulic Institute Engineering Data Book (HI EDB) is a foundational technical reference for engineers, pump manufacturers, and end-users involved in fluid transfer systems. Originally evolving from early 20th-century standards, this book provides the comprehensive data needed to design, analyze, and optimize pumping systems. Overview and Purpose

1. Variable Frequency Drive (VFD) Applications

• How affinity laws change with slower speeds.
• Minimum speed limits to avoid overheating bearings.
• Calculating harmonic distortion effects on pump motors.

• Vapor pressure curves for thousands of fluids.
• Atmospheric pressure correction charts for high-altitude installations.
• Safety margins for NPSH available (NPSHa) versus NPSH required (NPSHr).
