Specification of pressure and volume (PV flash)
Compute the properties of a given fluid, at a fixed pressure and volume.
Function signature
Function parameters
The function takes the following arguments:
- Fluid: TEXT
The name of the fluid. The list of available fluids can be found here.
- P: NUMBER
The pressure at which the properties are to be computed. The pressure unit depends on the units specified in the
in-unitsparameter. The default unit isPa.- V: NUMBER
The volume at which the properties are to be computed. The volume unit depends on the units specified in the
in-unitsparameter. The default unit is㎥/kg.- Properties: TEXT or TEXT array
The list of properties to be computed. The list of available properties can be found here.
- in-units: TEXT [optional]
A string specifying the units of the temperature and pressure. The default unit is
SI. The list of available units can be found here.- out-units: TEXT [optional]
A string specifying the units of the properties. The default unit is
SI. The list of available units can be found here.
Function results
Returns a value, or an array of values, corresponding to the list of properties of the fluid at the given pressure and volume.
