What do "L/min" and "GPM" measure in fluid power?

"L/min" stands for liters per minute and "GPM" stands for gallons per minute. Both units are used to measure flow rates in fluid power systems. Flow rate is a critical parameter in hydraulic systems as it indicates the volume of fluid that passes through a given point in a system over a specified period.

Understanding flow rates is crucial in designing and troubleshooting fluid power systems, as adequate flow is necessary to ensure that components such as pumps, actuators, and valves operate effectively and efficiently. When operators know the flow rates in their systems, they can assess the performance, predict system behavior under different conditions, and make necessary adjustments to maintain optimal performance.

The other options are focused on different characteristics of fluid power systems, such as pressure, temperature, and viscosity, which are important but do not pertain specifically to the measurement of flow rates.
