system.thermo.if97.compressibility
Calculates isothermal compressibility.
Syntax
system.thermo.if97.compressibility(p, t) # Pressure and Temperature
system.thermo.if97.compressibility(p, h) # Pressure and Enthalpy
system.thermo.if97.compressibility(p, s) # Pressure and Entropy
system.thermo.if97.compressibility(h, s) # Enthalpy and Entropy
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 - Isothermal Compressibility (1/Pa)
A measure of a substance's change in volume in response to pressure changes at constant temperature.
Scope
Gateway, Designer, Client, Perspective Session
Example
Pressure and Temperature
p = 800000
t = 475
result = system.thermo.if97.compressibility(p=p, t=t) # Call correct overload
print result
