IsothermalCompress

 

The IsothermalCompress function returns the isothermal compressibility of a fluid, which is defined by

 

 

For an ideal gas, the isothermal compressibility is inverse pressure.

 

The isothermal compressibility for some incompressible substances is provided as a function of  temperature.

 

 

Examples:

 

$UnitSystem SI K kPa mass

T=870 [K]

P=35000 [kPa]

beta_T=isothermalcompress(Steam,T=T,P=P)

InverseP=1/P

 

  

{Solution:

InverseP=0.00002857 [1/kPa]

beta_T=0.00003466 [1/kPa]

}

 

 

$Load Incompressible

$UnitSystem SI kPa K

beta_T=isothermalcompress(CO2_solid,T=190 [K])

 

{Solution:

beta_T=2.100E-07 [1/kPa]

}
