property T_at_min: float

Temperature value corresponding to the minimum value of the property correlation function within the validity range

Type:

float

compute_bounds() → None

Computes the bounds of the property within the validity range, i.e., the minimum and the maximum values of the correlation function inside the validity range, together with the corresponding temperature values. If this method is not invoked, the default values are -nan for the minimum value of the property and for its corresponding temperature, and nan for the maximum value of the property and for its corresponding temperature. The bounding values are computed using the scipy.optimize.minimize_scalar() function by adopting the “Bounded” method (for more details, please refer to the scipy documentation).

Return type:

None

property correlation_name: str

Name of the correlation

Type:

str

info(T: float, p: float = scipy.constants.atm, print_info: bool = True, n_tab: int = 0) → None | str

Prints the information about the property and about the correlation adopted to compute its value.

Parameters:

• T (float) – Temperature in \([K]\)

• p (float, optional) – Pressure in \([Pa]\), by default the atmospheric pressure value, i.e., \(101325.0 Pa\)

• print_info (bool, optional) – True to print to the console, False for getting the string. By default, True

• n_tab (int, optional) – Number of indentation tabs used to format the output, by default 0

Returns:

Returns None if print_info=True, otherwise returns the content of the information.

Return type:

None | str

initialization_helper(property_value: float) → float | None

Returns the temperature guess value according to the value of the property passed as argument. It is used by the root finder algorithm in case the return type is not None.

Parameters:

property_value (float) – value of the property
