← ScienceWhich mechanism causes increased drag in turbulent airflow?
A)Momentum diffusion from turbulent eddies✓
B)Decreased pressure behind the object
C)Increased flow laminarization near surface
D)Suppressed boundary layer separation
💡 Explanation
Momentum diffusion increases drag because it transports momentum away from the main flow and dissipates energy through chaotic movement creating turbulent eddies. Therefore, momentum diffusion causes drag rather than drag arising solely from pressure differences.
