What is Pascal’s Law?
Pressure is defined as the ratio of the force applied and the cross-sectional area. In 1653, Blaise Pascal published his book The Physical Treatises of Pascal in which he discussed the principles of static fluids. He observed that pressure in a fluid at rest is the same at all points if these points are at the same depth and if we apply external pressure to this fluid, all the applied force is distributed throughout the liquid.
In other words, all the externally applied static pressure on a confined liquid is equally transmitted throughout the liquid in all directions.
Pascal’s Law
Pascal’s law establishes the relation between pressure and the height of static fluids. A static fluid is defined as a fluid that is not in motion. When the fluid is not flowing, it is said to be in hydrostatic equilibrium. For a fluid to be in hydrostatic equilibrium, the net force on the fluid must be zero. This law can be applied to a wide range of real-life applications and hydraulic machines are one of the widely used applications of this law. These hydraulic systems allow us to design shockers and heavy-lifting machines.
