Disjoining pressure can be expressed as: $${\displaystyle \Pi _{d}=-{1 \over A}\left({\frac {\partial G}{\partial x}}\right)_{T,V,A}}$$ where (in SI units): Πd - disjoining pressure (N/m )A - the surface area of the interacting surfaces (m )G - total Gibbs energy of the interaction of the two surfaces (J)x - … See more In surface chemistry, disjoining pressure (symbol Πd) according to an IUPAC definition arises from an attractive interaction between two surfaces. For two flat and parallel surfaces, the value of the disjoining See more • Capillary condensation • Capillary pressure • Hamaker constant • Thin-film equation See more Webthe disjoining pressure and the curvature of the interface. Rigorously, the recoil pressure and the viscous stress could also influence the saturation temperature but, for the con-ditions studied on this paper, their role is negligible. Note that, when the molecular interactions are opposed to evap- WebNote that the term disjoining pressure is misleading, because the force can be either disjoining (repulsion between surfaces) or conjoining (attraction between surfaces). … mary astrology
