Operating Viscosity Calculator

Knowing the viscosity of any fluid you are trying to pump is key. As viscosity tends to change with temperature for most fluids, being able to accurately calculate viscosity across a range of operating temperatures is vital in determining if a pump can even handle a viscous fluid at lower start-up temperatures. Measured in centistokes (cSt) in honor of George Stokes, water at 20°C is used as a reference and has a base value of 1 cSt. To calculate your operating viscosity using our calculator, you’ll need viscosity vs. temperature properties for your fluid along with your operational temperatures.
