What is a true basic concept of fluid power?

• A. Colored fluid is used for classification
• B. Fluid will take the path of least resistance
• C. Hydraulic pumps create pressure
• D. Fluid power has a disadvantage compared to pneumatic in power

Answer: (B)

In fluid power, the driving force is pressure, and the fluid will move along routes that offer the least opposition. When you have a junction with several possible paths, the same pressure pushes more fluid through the path that has fewer restrictions—wider passages, lower friction, or fewer control limitations—so that most of the flow follows the easier route. This explains how flow splits in a network: it favors the path of least resistance, and the other paths take only the portion determined by their higher resistance. Color of the fluid, while sometimes used for identification, isn’t a fundamental concept. The idea that hydraulic pumps simply “create pressure” glosses over the fact that pressure in a system results from resistance to flow; pumps provide energy and flow, but pressure builds where loads resist that flow. And while fluid power can deliver substantial force, it isn’t about one technology being universally stronger than the other—the basic principle here is how flow chooses its path.
