Fluid Kinematic Viscosity Modules

Calculate dynamic viscosity and kinematic viscosity for single phase liquids.

Kinematic viscosity is equal to the dynamic viscosity divided by the density of the fluid. The specific gravity (SG) equals the fluid density divided by the density of water (1000 kg/m^3). For liquids lighter than or equal to water the density can be defined as degrees API, or degrees Baume (Be-). For liquids heavier than water the density can be defined by degrees Baume (Be+), or degrees Twaddell.

Calculate Saybolt universal seconds (SUS), and Saybolt Furol seconds (SFS) for a single phase liquid.

Saybolt viscometers are used to measure liquid viscosity by the time taken for a specified quantity of the liquid to flow downwards through a vertical tube. Viscosity can be entered as either

• Dynamic viscosity
• Kinematic viscosity
• Saybolt Universal Seconds (SUS) measured at 100 F
• Saybolt Universal Seconds at time T (SUST) measured at temperature T
• Saybolt Furol Seconds (SFS122) measured at 122 F
• Saybolt Furol Seconds (SFS210) measured at 210 F

Saybolt Universal seconds are measured with the universal tip. Saybolt Furol seconds are measured with the Furol tip. Saybolt Furol seconds are used for viscous liquids. The Saybolt viscometer is not suitable for fluids with a viscosity less than 1.8 centi Stokes (cSt), or 1.8e-6 meters square per second (m^2/s).

Calculate the dynamic viscosity and kinematic viscosity of water and steam using the IAPWS R12-08 industrial equation (u2 = 1).

The viscosity can be either calculated directly from temperature and density, or from temperature and pressure using IAPWS R7-97 to calculate the density.

Note : There is an anomaly in the calculated density and viscosity close to the critical point. Refer to the help pages for more details (click the utility button on the data bar).
