PSV and Rupture Disc force calculation (based on API RP 520) Pipemill: for the design, analysis and layout of piping components Force calculations for the initial or ‘pop’ condition and under sustained flow may be carried out for gas and vapour PSV’s (pressure safety valves) discharging into a closed header, or directly to atmosphere.
Be able to resolve a resultant (net) force into orthogonal (perpendicular) components using vector resolution: A 72-kg sprinter is acted upon by a resultant ground reaction force of 2124 N. The force acts at an angle that is 86 degrees above a fixed horizontal axis (the ground). From equation (2) it can be seen that if M is varying continuously, zero shearing force corresponds to either maximum or minimum bending moment. It can be seen from the examples that "peaks" in the bending moment diagram frequently occur at concentrated loads or reactions, and these are not given by ; although they may in fact represent the ...
