Potential Energy and PSI

  1. Sep 11, 2010 #1
    I wasn't sure exactly where I should have posted this but here I go....

    I was reading that Voltage is a measure of potential energy. With that same mind frame would it be correct to say that PSI is also a measure of potential energy? Specifically referring to the psi in an pneumatic line for say a tool.

    Pressure is not energy, it is force per unit area (pounds per square inch, for example), wheras energy has length*force units (inch-pounds, for example). However, since pressure has the ability to do work, pressure (gas / liquid) may be considered as pressure energy density (energy per unit volume), but Potential Energy density is not the right term here.
