Applications of Pascal’s Law

The application of Pascal’s Law can be seen throughout industries. Some of the applications are as follows:

  • Hydraulic Lift
  • Hydraulic Jack

Now let’s learn about them in detail.

Hydraulic Lift

By applying Pascal’s Law of transmission in real life, we can use it to lift heavy equipment such as cars, trucks, cargo containers, etc. As the ratio of force and the cross-sectional area remains constant throughout the liquid, applying a small force to the small cross-sectional area can exert higher force at a high cross-sectional area, so that ratio remains the same. The image added below shows a hydraulic lift lifting a vehicle.

 

Hydraulic Jack

Hydraulic Jacki is the less powerful version of the Hydraulic lift which can help us lift our cars or heavy motor vehicles partially for maintenance and other purposes. It uses the same principle but on a small scale. The hydraulic jack is shown in the image below.

Other than the above-mentioned use cases Hydraulic Braking Systems and Hydraulic Pumps also leverages the same principles to stop cars/heavy motor vehicles and pump water respectively. 

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.

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....

Pressure is defined as the ratio of the Force and cross-sectional area on which that force is applied, mathematically we can represent the same as follows:...

Difference of Pressure in Column

The figure shows a cylindrical element submerged in the fluid of density ρ, of area A and height h. Let the pressure at the top of the element be P1 and P2 at the bottom. Let us assume that the weight of the liquid is “mg” in this element. Then the difference in pressures between the two points is given by,...

Pascal’s Law Definition

Pascal’s law states that whenever external pressure is applied to any part of a liquid. This pressure gets distributed in all directions equally. A number of devices are based on this principle. The hydraulic lift is also an application of this law....

Pascal’s Law Derivation

Let us consider a right-angled triangle(with sides p, q, and r) prism (height s) submerged in the liquid of density ρ, also assume the size of the submersed element is negligible with compare to the volume of the liquid, and all the points on the element experience the same gravitational force....
