Capillary pressure

Input(s)

$\sigma$: Fluid interfacial Tension $(\mathrm{dyn} / \mathrm{cm})$

$\theta$: Angle of Wettability (degree)

$r$: Radius of Capillary $(\mathrm{cm})$

Output(s)

$P_{C}$: Capillary Pressure $(\mathrm{dyn} / \mathrm{cm})$

Formula(s)

$$ P_{C}=\frac{2 * \sigma * \cos (\theta)}{r} $$
