RP.rho_compressed

 

The procedure RP.rho_compressed provides the density of compressed liquid as a function of temperature and pressure.

 

Call RP.rho_compressed(F$,T,P,M$:rho)

 

Inputs:

F$   Fluid name

T    Temperature (C,K,F, or R)

P    Pressure (Pa, kPa, bar, MPa, psi, or atm)

M$ String indicating the method to use: 

 'COSTALD' = COSTALD CSP method 

 'CZ1' = Chang Zhao method derived from 5th Edition of Gases and Liquids

 'CZ2' = Chang Zhao method described in Molecular Liquids 160 (2011) pp. 94-102

 'Nasrfar' = Nasrfar Moshfeghian method

 

Outputs:

rho   Density of compressed liquid (kg/m^3, kmol/m^3, lbm/ft^3, lbmol/ft^3)

 

Example

$UnitSystem SI Mass J K Pa

T=400 [K]

P = 8e6 [Pa] 

F$='RP1'

M$ = 'COSTALD'

Call RP.rho_compressed(F$,T,P,M$: rho)

 

Solution

{rho = 739.6 [kg/m^3]}
