Question

In a fluid coupling, power is transferred due to:

• A. Change in pressure of the circulating fluid
• B. Change of mechanical energy to fluid energy
• C. Change in kinetic energy of the circulating fluid
• D. Conversion of fluid energy to mechanical energy

Hint:

Understanding how fluid couplings work can help in applications where smooth startup and variable load conditions are needed, as they can reduce shock loads and adjust mechanical power output.

Answer 1

The Correct Option is B

Fluid couplings transfer power by converting the mechanical energy of one part (usually a rotating drive shaft) into fluid energy and then back into mechanical energy on the driven side. This involves the acceleration and deceleration of fluid in a sealed chamber, transferring energy without direct contact between mechanical components.
