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