Liquid

Single component physical properties: Liquid Equation 2 for the bulk modulus is still valid for the liquid:

And after a first integration:

Depending of the type of fluid properties chosen, the liquid bulk modulus and density will be computed as:

• For elementary and elementary with calculated viscosity type of fluid properties, the liquid bulk modulus is constant , then we obtain for the liquid density:

For elementary the density is not dependent of the temperature:

Then: Equation 6: Elementary liquid density

• For advanced and advanced with calculated viscosity types of fluid properties, the liquid bulk modulus is linear in function of the pressure through the slope of bulk modulus α [%]:

Which gives after integration: Equation 7: Advanced liquid density

If the slope α = 0, the elementary results can be applied.

• For “advanced using tables” type of fluid properties, depending of the definition mode chosen, the liquid density and/or the bulk modulus are computed with respect to Equation 2. The tables data are linearly interpolated in both pressure and temperature directions.
