    Dynamic Viscosity cP [=mPa.s] Kinematic Viscosity cSt
    Density kg/m3

    Notes:
  • Kinematic viscosity = Dynamic viscosity / density, as the graphs are based on kinematic viscosity in cSt no input for density is required when US customary units are used.
  • The Viscosity Correction factors are applicable per impeller so for multistage pumps the head should be specified per stage.
