Question

The correct statement, for a flow across an oblique shock is

• A. component of velocity normal to shock decreases while tangential component increases
• B. component of velocity normal to shock increases while tangential component decreases
• C. component of velocity normal to shock is preserved while tangential component decreases
• D. component of velocity normal to shock decreases while tangential component is constant

Hint:

Tangential velocity remains constant; normal velocity decreases across oblique shock.

Answer 1

The Correct Option is D

In oblique shocks, the normal velocity component drops due to compression, while the tangential component remains unchanged across the shock.
