A Caution message in AFT Fathom
This message displays for centrifugal pumps which use viscosity corrections to the performance curves. The methodology used by the Hydraulic InstituteANSI/HI Standard 9.6.7-2021, Rotodynamic Pumps - Guideline for Effects of Liquid Viscosity on Performance, 2021, published by Hydraulic Institute, 300 Interpace Parkway, Building A, 3rd Floor, Parsippany, New Jersey, USA has limits which depend on flowrate, head rise, viscosity and RPM. If the operating case in AFT Fathom is outside the valid range this warning displays.
