In a hydraulic system, what is the purpose of using incompressible fluids?

In a hydraulic system, the use of incompressible fluids is crucial because it ensures that pressure changes are transmitted uniformly throughout the system. When the fluid is incompressible, any change in pressure at one point in the system will result in an equal change in pressure at all other points. This property allows for effective and precise control of hydraulic devices, such as lifts, brakes, or machinery.

Using incompressible fluids maintains the efficiency of the hydraulic system since any applied force translates directly into movement or action without the fluid's volume changing significantly. This is essential for the reliable operation of hydraulic systems, as it allows for predictable performance and efficient energy transfer.
