What does a filled triangle represent in a fluid power diagram?

• A. Hydraulic Flow
• B. Pneumatic Flow
• C. Pressure
• D. Temperature

Answer: (A)

In fluid power diagrams, symbols on lines convey how the fluid moves. A filled triangle placed on a line is used to indicate the direction of flow, and in the context of a hydraulic (liquid) circuit, that triangle represents hydraulic flow. The fill and shape help distinguish this as a flow indication for liquid movement rather than a property like pressure or temperature, and it’s tied to the conventions used for hydraulic systems rather than pneumatic (gas) systems. The other options describe conditions or types of flow that aren’t conveyed by this symbol in a hydraulic schematic.
