WebWhen a fluid is not flowing, we say that the fluid is in static equilibrium. If the fluid is water, we say it is in hydrostatic equilibrium. For a fluid in static equilibrium, the net force on any part of the fluid must be zero; otherwise the fluid will start to flow. WebFeb 23, 2005 · In this case there is a flow diverter making sure the power steering gets it share. There may always be a slight demand on the power steering circuit. This pressure will show up in front of the flow diverter. On a two pump system, I would expect the hydraulic device side pressure to be real close to 0 with no demand.
