    Study Notes

    Pressure Element Principles

    • Pressure is a measure of the force applied to a unit area.
    • Force is the pushing or pulling that can cause an object to move or change shape.
    • Force can be applied in any direction.

    Calculating Pressure

    • Pressure (P) is calculated by dividing the force (in pounds) by the area (in square inches): P = Force / Area
    • Example: A 50-pound block measuring 10 square inches on each side is placed on a table of the same size, resulting in a pressure of 5 psi.

    Units of Pressure

    • The most common unit of pressure is pounds per square inch (psi).

    Pressure Scales

    • There are three common scales for measuring pressure:
      • Gauge Pressure Scale
      • Absolute Pressure Scale
      • Vacuum Pressure Scale
