This law states that pressure applied to a confined fluid is transmitted undiminished in all directions. It states that pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid, regardless of the shape of the container. Pascal’s Law has numerous practical applications, including hydraulic systems, hydraulic presses, hydraulic lifts, and brake systems in vehicles. It forms the basis for understanding the behavior of fluids under pressure and is essential in engineering and technology where fluid power is utilized. Mathematically, it can be expressed as

where

• $P$ is pressure,
• $F$ is force,
• $A$ is area.
