What is Collapse Pressure? - Definition from Petropedia

Collapse Pressure is the pressure which is supplied from the outside of a pipe. When the Collapse Pressure is higher than the rated or designed Collapse Pressure of the pipe, then the pipe crushes or collapses. In other words, when the differential pressure from outside to inside the tube or vessel increases, the tube deforms catastrophically.

4. FLUID SATURATION AND CAPILLARY PRESSURE 4.1 Fluid

The interfacial forces give rise to what is known as a capillary pressure.Capillary pressure is the difference in fluid pressure across an interface between two fluids in a confined volume. In the discussion of capillary pressure, we will first examine surface energy and wettability, and then go on to derive a general expression for capillary
