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.
