Why is pressure in a liquid the same in all directions?
2012年7月12日 When a milliliter of liquid is at rest, it means that in this milliliter of material, the molecules are randomly ordered and randomly moving so that their centerofmass remains at rest But when it's so, the only "forcerelated" quantity by which one milliliter of this liquid differs from another is the density or any function of it, such as the pressureHydraulic gradient can also be represented in three dimensions when flow is not aligned with a coordinate axis, x, y, or z (Equation 23), so there is a component of flow in each axis direction as shown in Equation 23 In this case, in order to 43 Hydraulic Gradient – Hydrogeologic Properties of 2008年9月1日 Hydraulic systems may be very complex, but every system, no matter how basic, must contain a reservoir, a pump, various valves to control oil flow, direction and pressure, and a hydraulic cylinder or motor to move the load applied by oil under pressure (see Figure 1) Hydraulic system operating principlesTroubleshooter’s Guide To Hydraulic System Problems MRO 2020年3月9日 Unlike centrifugal pumps, in which flow depends on pressure, hydraulic systems use positive displacement pumps and motors in which flow is independent of pressure No pump is 100% efficient, so pressure always influences flow to some extent Hydraulic systems produce kinetic energy in the form of flow and potential energy in the form of pressureGetting the Most Efficiency Out of Hydraulics Power Motion
