What happens if the pressure applied to a hydraulic system exceeds the fluid’s ability to transmit it?
Pascal’s law assumes an incompressible fluid. If pressure exceeds the fluid’s incompressibility limit, the fluid compresses or the system fails (e.g., leaks or bursts), as the assumption of uniform pressure transmission breaks down.
