The fluid must be incompressible: Pascal's principle only holds true for fluids that are incompressible, meaning their density and volume remain constant under pressure. This condition ensures that the pressure applied at one point in a fluid is transmitted equally throughout the entire fluid.
The fluid must be pure and homogenous: In order to have consistent transmission of pressure, the fluid must be free from impurities or variations in its composition. This ensures that the fluid behaves uniformly and constantly throughout the system.
The hydraulic pistons must have the volume: Pascal's principle is observed in hydraulic systems, where pressure is transferred through a fluid enclosed within pistons. The pistons must have a defined volume to allow for the transmission of pressure. As pressure is applied to one piston, it is transmitted to the fluid, which then exerts the same pressure on the other piston.
The walls of the container enclosing the fluid must be airtight: To maintain the integrity of pressure transmission, the container enclosing the fluid must be airtight. This ensures that pressure is not lost or affected due to leaks in the system. Airtight walls prevent the escape of fluid or the entry of air, preserving the pressure applied to the system.
The output piston must be larger than the input piston: In hydraulic systems, the output piston, which receives the transmitted pressure, is typically larger in size compared to the input piston. This size difference amplifies the force exerted by the fluid, resulting in mechanical advantage. This mechanical advantage allows for the multiplication of force applied at the input piston to produce a greater force at the output piston.
