Which flow transition is implied while increasing power on a ship's propeller?

💡 Explanation

Higher Reynolds number results from increased velocity, creating a shift to turbulence within the propellor's boundary layer; because laminar flow becomes unstable, therefore turbulent flow increases drag and noise rather than separation, which requires flow reversal.
