🔍 Key Concepts

• Hydraulic coupling operation – how torque is transmitted through a fluid between an impeller (driver) and runner (driven member) • Slip in fluid couplings – what ‘slip’ means and why it exists in a hydraulic coupling • Difference between normal operating slip and special conditions like vibration or axial thrust

💭 Think About

• Ask yourself: In a hydraulic (fluid) coupling, can the driven runner turn at exactly the same speed as the driving impeller and still have the fluid vortices that transmit torque? Why or why not? • Which of the choices directly relates to a steady difference in speed between the impeller and runner, rather than a brief or unrelated mechanical effect? • Think about what must exist continuously for energy transfer in the liquid vortex to occur: is it a force along the shaft, a temporary vibration, or a speed difference between input and output?

✅ Before You Answer

• Make sure you are clear on the definition of slip in a hydraulic coupling (difference in speed between impeller and runner). • Check which options describe a continuous operating condition (always present when the coupling is transmitting torque) rather than a short-term or secondary effect. • Verify that the option you pick is directly tied to vortex formation and energy transfer in the fluid, not to gear forces or shaft vibrations.
