# What is Pascal Principle definition/concept

In relation to hydrostatics and fluid mechanics there is a basic principle known as the Pascal Principle. According to him, the pressure exerted by the fluid contained in a container is always fixed and constant in all directions. This means that from a very small force it is possible to move an object of great weight. This phenomenon occurs due to the action of pressure, which is equal to the force exerted divided by the surface (the force is measured in newtons and the surface in square meters). Because the pressure is the same in all parts, the relationship between the forces and the surface remains constant.

When a water-filled plunger is connected to a hollow sphere with holes on its surface and pressure on the plunger is exerted, the result is that water comes out of all orifices in the sphere with the same pressure. This particular example goes beyond the operation of a hydraulic press, the brake mechanism of an automobile and cooling systems. Pascal Principle

Pascal’s principle not only explains the operation of hydraulic devices or the behavior of a fluid inside an enclosure, but also allows us to understand the effect of the atmosphere on liquids.

The importance of the Pascal Principle also expresses a curious fact: in the international system of units there is the pascal, a unit of pressure whose symbol is Pa and named after Blaise Pascal.

### This man of science from the 17th century and of French nationality died at 39 years old

He has gone down in history because of his research into fluids and hydrostatics, as well as in many other areas of knowledge. Thus, in geometry there is the famous Pascal triangle, which in the calculation of probabilities is considered a precursor, and in terms of technology, he developed a very advanced mechanical calculator for that time. In this sense, some historians of science believe that some of Pascal’s contributions represent one of the first theoretical views in the field of information technology . Pascal Principle

After suffering an accident from which he was miraculously unscathed, Pascal abandoned his scientific research and devoted himself to theology and philosophy, two fields of knowledge that once again showed his intellectual value. In philosophy he maintained a rationalist stance and in theological questions he tried to reconcile the principle of Christian faith with the principles of reason.
