🔍 Key Concepts

• Hydraulic system pressure vs. flow – what actually causes pressure to drop slowly over time in a running system • Behavior of a bleeder (relief/drain) valve if it is stuck open vs. closed • Effect of fluid temperature and viscosity (cold vs. warm oil) on pump pressure and flow

💭 Think About

• Ask yourself which option would let oil continuously leak or bypass back to the reservoir, slowly reducing system pressure while the pump keeps running • Decide which options would more likely cause an immediate, obvious failure (no movement / no pressure) rather than a gradual decrease in pressure • Think about whether cold hydraulic fluid would more likely cause high pressure or low pressure at start‑up, and how that changes as it warms up

✅ Before You Answer

• Identify the choice that creates a continuous loss path for hydraulic fluid from the pressure side back to the tank • Eliminate any choices that would cause sudden loss of motion/pressure instead of a gradual drop • Consider how temperature affects viscosity: thicker (cold) oil vs. thinner (hot) oil and which condition matches a gradual pressure decrease
