system.thermo.if97.vaporFraction
Calculates vapor fraction.
Syntax
system.thermo.if97.vaporFraction(h, s) # Enthalpy and Entropy
system.thermo.if97.vaporFraction(p, h) # Pressure and Enthalpy
system.thermo.if97.vaporFraction(p, s) # Pressure and Entropy
system.thermo.if97.vaporFraction(t, s) # Temperature and Entropy
info
This function must be called with named parameters.
Parameters
| Type | Parameter | Description |
|---|---|---|
| Double | h | Specific Enthalpy (J/kg) |
| Double | s | Specific Entropy (J/(kg·K)) |
| Double | p | Absolute Pressure (Pa) |
| Double | t | Temperature (K) |
Returns
Double - Vapor Fraction (Quality) (0 to 1)
The fraction of the substance in the vapor phase
Scope
Gateway, Designer, Client, Perspective Session
Example
