How to Calculate Force Based on Pressure - dummies

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. In the foot-pound-second (FPS) system, the units are pounds per square inch, or psi.

Barlow's Formula - Internal, Allowable and Bursting Pressure

Mill Test Pressure. The "Mill Test Pressure" refers to the hydrostatic (water) pressure applied to the pipe at the mill to assure the integrity of the pipe body and weld. P t = 2 S t t / d o (4) where. P t = test pressure (psig) S t = specified yield strength of material - often 60% of yield strength (psi) Wall Thickness
