A crude oil pipeline is designed for 140°F (low viscosity). At startup, the oil is 60°F (high viscosity). Section E (Viscous Correction) provides factor charts. The engineer inputs the cold viscosity, finds that friction loss is 4x higher, and specifies a VFD (Variable Frequency Drive) for slow ramp-up, preventing motor overload and cavitation.
for every imaginable fitting, from 90-degree elbows to check valves. hydraulic institute engineering data book
Before digital simulation, pump system design was a craft passed down through handwritten notes, slide rules, and field experience. The HI Data Book codified that wisdom. Flipping through its pages is like reading the collected secrets of thousands of pump stations, refineries, and water treatment plants — failures and all.

The latest iterations of the Data Book have expanded into modern challenges: The engineer inputs the cold viscosity, finds that
