In fluid statics, capillary pressure ($${\displaystyle {p_{c}}}$$) is the pressure between two immiscible fluids in a thin tube (see capillary action), resulting from the interactions of forces between the fluids and solid walls of the tube. Capillary pressure can serve as both an opposing or driving force for fluid transport … See more Capillary pressure is defined as: $${\displaystyle p_{c}=p_{\text{non-wetting phase}}-p_{\text{wetting phase}}}$$ where: $${\displaystyle p_{\text{c}}}$$is the capillary pressure See more It has been shown that as reservoir simulators use the primary drainage capillary pressure data for saturation-height modeling … See more • Capillary action • Capillary number • Disjoining pressure • Leverett J-function See more Capillary pressure formulas are derived from the pressure relationship between two fluid phases in a capillary tube in equilibrium, which is that force up = force down.
