We are taught to think of fluid power in terms of flow and pressure; flow is for velocity and pressure is for force. While this is true at the actuator (the motor or cylinder), the terminology may have limited us in our approach to energy transfer. It is necessary to separate flow and pressure in the initial calculations for what is required for the actuator. The required speed will determine the rate that fluid enters the actuator. The force required will determine the pressure of that fluid. This is pretty straightforward, and it provides necessary information when using a single-fixed flow to drive a single-fixed load.
