Pressure maybe exerted in one direction, in several directions, or in all directions. Computing Force, Pressure, and Area A formula is used in computing force, pressure, and area in fluid power systems. In this formula, P refers to pressure, F indicates force, and A represents area. Force equals pressure times area. Thus, the formula is written Equation 2-1.
Pressure equals force divided by area.
By rearranging the formula, this statement may be condensed into Equation 2-2. Since area equals force divided by pressure, the formula is written Equation 2-3. Device for determining the arrangement of the force, pressure, and area formula. Figure 2-1 illustrates a memory device for recalling the different variations of this formula. Any letter in the triangle may be expressed as the product or quotient of the other two, depending on its position within the triangle.
