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.

 

 

Example:

 

$UnitSystem SI K kPa mass

T=870 [K]

P=35000 [kPa]

K_T=isothermalcompress(Steam_IAPWS,T=T,P=P)

InverseP=1/P

  

{Solution:

InverseP=0.00002857 [1/kPa]

K_T=0.00003466 [1/kPa]

}
