Question 1 of 27070

The pressure of an operating hydraulic system, as indicated by a pressure gauge, is a result of the fluid flow overcoming __________.

🔍 Key Concepts

• Basic hydraulic principle: Pressure builds when flow meets resistance • Difference between flow resistance in pipes and load resistance at the actuator (cylinder/ram) • How a pressure gauge measures system pressure at its location

💭 Think About

• When a pump is running but the actuator (cylinder) is not moving, what is creating the pressure the gauge sees? • If you increase the external load on a hydraulic cylinder, what happens to system pressure, and why? • Could pressure exist in a hydraulic system even with no external load, and what would cause it?

✅ Before You Answer

• Be clear on what creates pressure vs what allows flow • Decide whether pressure comes from only one type of resistance or multiple resistances together • Think about what the gauge is actually sensing: pressure at that point in the line, regardless of where the resistance comes from

Question 1 of 27070

internal resistance to flow

resistance of the internal components

the load applied to the system
