Force and Speed in Hydraulic System

Here’s another Flint Hydraulics Tech Tip: The relationship between force and speed applies to all motion, no matter the means of transmitting power. When power is transmitted through a hydraulic system, speed is measured as flow rate – usually gallons per minute – and force is measured as pressure – usually pounds per square inch. An increase in speed or force means the power requirement goes up. If the flow rate (speed) of a hydraulic system doubles, the power from the system doubles. If the pressure (force) doubles, the power output of the system doubles. If both flow rate and pressure double, the output power of the system quadruples. Want to maximize your system’s efficiency?
