The Beginner’s Guide to Hydraulics: What Are Hydraulics ...
hydraulicsonline.comFirst, we can calculate the pressure of the liquid inside piston A using the equation for calculating pressure: Pressure (P) = Force (F) ÷ Cross-Sectional Area (A). In the example below P = 30 ÷ 0.2, so P = 150 Pa The pressure within this closed system is transmitted equally in all directions, therefore the pressure in piston B is also 150 Pa.
