Which consequence results when supersonic airflow encounters surface irregularities?

💡 Explanation

Increased skin friction drag results because transition to turbulence occurs due to surface irregularities disrupting laminar flow. This transition increases momentum transfer near the surface, therefore drag rises, rather than heat transfer decreasing, which it might in other scenarios.
