Introduction to Pressure in Fluid Mechanics. 1  Pressure always acts inward normal to any surface (even imaginary surfaces as in a control volume). 2  Pressure is a normal stress, and hence has dimensions of force per unit area, or {ML-1T-2}. In the English system of units, pressure is expressed as psi or lbf/in2.
There are two different types of pressure, hydrostatic pressure and formation pressure. So, by definition, hydrostatic pressure is the total fluid pressure created by the weight of a column of fluid, acting on any given point in a well. Hydrostatic pressure = fluid density *conversion factor * true vertical depth .
