The power loss associated with slip in a...

🔍 Key Concepts

• Fluid coupling basics – how power is transmitted through hydraulic fluid between driving and driven members • Slip in a fluid coupling – what it means when input speed and output speed are different • Energy conservation – if mechanical power isn’t transmitted as rotation, where does it go?

💭 Think About

• Think about what happens to the kinetic energy of the fluid inside the coupling when there is slip between the driving and driven members. • Consider which option represents a common by‑product when mechanical energy is not fully converted into useful work in rotating machinery. • Ask yourself: in real machinery, which effect would be continuous and proportional to the amount of slip, rather than brief or intermittent?

✅ Before You Answer

• Verify which choice describes a continuous loss of energy, not just a momentary symptom like noise or vibration. • Check which effect would most likely require cooling or temperature monitoring in real fluid coupling installations. • Eliminate options that mainly describe mechanical problems in components rather than the normal physical result of power loss in a fluid.

The power loss associated with slip in a fluid coupling appears as __________.

chattering in the driving member

heat in the hydraulic fluid

vibration in the driving member

leakage around the ring valve
