← ScienceWhich flow change increases drag coefficient downstream because a ship exceeds critical speed?
A)Increased skin friction resistance
B)Amplified hydrostatic pressure gradient
C)Advancement toward cavitation inception
D)Transition towards turbulent boundary layers✓
💡 Explanation
The transition increases drag because exceeding critical Reynolds Number promotes boundary layer transition to turbulence. A turbulent boundary layer has higher skin friction and pressure drag, therefore total drag rises dramatically due to turbulence, rather than laminar effects.
