appliedchemlabwork_tayra.A3.calc_relative_viscosity

appliedchemlabwork_tayra.A3.calc_relative_viscosity(t: ndarray[tuple[Any, ...], dtype[floating[Any]]], t_0: float | floating[Any]) → ndarray[tuple[Any, ...], dtype[floating[Any]]]

Calculates the relative viscosities.

Parameters:

tNDArray[floating[Any]]

The time of the flows.

t_0Any floating number

The time of the flows.

Returns:

viscosityNDArray[floating[Any]]

The viscosities.

Notes

This calculates the viscosity with an approximation formula following below:

\[\eta_{\mathrm{r}} \approx{} \frac{t_1}{t_{\mathrm{s}}}\]

Please note that this approximation is good if the concentration of the solution is enough low. If you are using a highly concentrated solution, please use other method than viscosity method. Viscosity method is not suitable for calculating the molecular weight from the concentrated solution data.
