Liquid Pipeline Fluid Density Viscosity And Specific Gravity

Calculate single phase liquid density, specific gravity, degrees Baume, degrees Twaddell, and degrees API.

For liquids lighter than or equal to water the density can be defined as degrees API, or degrees Baume minus (Be-). For liquids heavier than water the density can be defined by degrees Baume plus (Be+), or degrees Twaddell.

CALCULATOR : Water Pipeline Sea Water Density And Viscosity From Temperature [FREE]   ±

Calculate seawater density and viscosity at atmospheric pressure from temperature, and practical salinity.

Seawater viscosity is calculated from fresh water viscosity using the equation from Sharqawy (2010). The fresh water viscosity is calculated from temperature and density using the IAPWS R12-08 industrial equations. Practical salinity = parts per thousand of dissolved solids (mainly salt). The absolute salinity is taken as 35.16504 / 35 times the practical salinity. The absolute salinity anomaly δSA is ignored.

Tool Input

  • T : Seawater Temperature

Tool Output

  • μ : Dynamic Viscosity
  • ν : Kinematic Viscosity
  • ρ : Seawater Density

CALCULATOR : Water Pipeline Fresh Water Density And Viscosity From Temperature [FREE]   ±

Calculate fresh water density and viscosity from temperature at atmospheric pressure (IAPWS R12-08 and IAPWS R7-97 steam table).

The calculation is valid from 0 to 100 degrees C. Use the Result Plot option to plot viscosity versus temperature.

Tool Input

  • T : Temperature

Tool Output

  • μ : Dynamic Viscosity
  • ν : Kinematic Viscosity
  • ρ : Density
