The Pressure-Flow Conundrum And What It Means For Hydraulic ...

Higher pressures mean higher force and torque is available from smaller components. And because the components are smaller in displacement higher speeds are possible from smaller flows. Smaller flows mean pipework valving and even the tank can be made smaller. So the power density of individual components and the system as a whole increases with pressure. But there are a number of ...
