Physics help, informations and practical use of physics
In hydraulic science, Physics help can be an advantage.
Hydrostatic energy is applied in most of the hydraulic systems.
Hydraulics field is controlled by Pascal's law. Check next, the connection between hydrostatic transmission and hydraulic transmission.
I will continue with Pascal. In the late seventeenth century Pascal discovered a Physics law that formed the fundamental basis for the science of hydraulics.
Pascal law is expressed as follows: Pressure applied on a confined fluid at rest is transmitted undiminished in all directions and acts with equal force on equal areas and at right angles to them.
Pascal’s law forms the basis for understanding the relationship between force, pressure and area.
Mathematically we express this relationship as follow:
F = P x A; P = F/A; and we can calculate area, A = F/P.
Pascal's law can be better pictured by the following example.
A bottle is filled with a liquid, which is not compressible. A force of 5 kg is applied to the stopper whose surface area is 4 cm². The area of the bottle bottom is 70 cm². If the stopper is pressed down into the bottle mouth, with a force of 5 kg such that it makes contact with the liquid, then the pressure exerted by the bottle is given by:
P = 5/4 = 1.25 kgf/cm²
This pressure will be transmitted undiminished to every square area of the bottle. The bottom of the bottle having an area of 70 cm² will be subjected to an additional force of:
F = P X A = 1.25 x 70 = 87.5 kgf
In hydraulic science, Physics can be an advantage.
Horsepower is a unit of measuring energy.
