system.thermo.if97.heatCapacityRatio
Calculates heat capacity ratio (Cp/Cv).
Syntax
system.thermo.if97.heatCapacityRatio(h, s) # Enthalpy and Entropy
system.thermo.if97.heatCapacityRatio(p, h) # Pressure and Enthalpy
system.thermo.if97.heatCapacityRatio(p, s) # Pressure and Entropy
system.thermo.if97.heatCapacityRatio(p, t) # Pressure and Temperature
info
This function must be called with named parameters.
Parameters
| Type | Parameter | Description |
|---|---|---|
| Double | h | Specific Enthalpy (J/kg) |
| Double | p | Absolute Pressure (Pa) |
| Double | s | Specific Entropy (J/(kg·K)) |
| Double | t | Temperature (K) |
Returns
Double - Heat Capacity Ratio (Cp/Cv)
Aso known as the adiabatic index, the ratio of specific heat, or Laplace's coefficient.
Scope
Gateway, Designer, Client, Perspective Session
