Pascal's Principle

#Physics

$\displaystyle P_{\text{in}}=P_{\text{out}}$

• The pressure going into a closed system is equal to the pressure exerted on another part of the closed system
• i.e. pressure is constant throughout the closed system
• Used to solve hydraulics problems

$\displaystyle F_{\text{out}}=\frac{A_{\text{out}}}{A_{\text{in}}}F_{\text{in}}$

• Expanded form used for hydraulics
