3、 transmitted equally and unchanged in all directions throughout the fluidhydraulic systems in a hydraulic lift system, an increased output force is produced because a constant fluid pressure is exerted on the larger area of the output pistonbernoullis principle as the speed of a fluid increases, the pressure within the fluid decreases more lif
