QuestionThe height a fluid will rise in a capillary tube is given as: $$H=\frac{2 \sigma}{\rho g r}$$
The fluid being tested has a specific gravity of $0.87[-]$. Use the graph shown to determine the surface tension ( $\sigma$ ) of the fluid used in this experiment, in units of kilograms per second squared $\left[\frac{\mathrm{kg}}{\mathrm{s}^{2}}\right]$.
