Depth ↔ Geostatic & Hydrostatic Pressure
Calculate overburden rock lithostatic pressure and fluid hydrostatic pressure at underground or deep ocean depths.
At 1000m deep, rock density of 2.7 g/cm³ exerts lithostatic overburden pressure. Fluid trapped in rock fractures at this depth would sustain hydrostatic pressure of 9.8 MPa.
