How fast does a hydraulic machine work? The model i am thinking of is a simple two-sided setup, where the surface areas of the two platforms are different and a tube connects them. In terms of movement of the two platforms, how fast can the machine work. I am just looking for an approximation, like can it be instantaneous or are hydraulic machines usually very slow-moving? Also, would the diameter of the tube connecting them (smaller than the diameter/surface area of either platform) affect the speed of the mechanism?
