A $0\mathrm{.}03$ cm internal diameter glass capillary tube contains gas, oil, and water, thus forming two interfaces, namely, gasoil and oilwater. The contact angles for these two interfaces are $35\backslash$deg and $25\backslash$deg $,$ while the surface and IFTs are $15$ and $30$ mN$/$m$,$ respectively. Calculate the gaswater capillary pressure
