Which statement about an oblique shock is INCORRECT?

  • A.The velocity component tangential to the shock is reduced across it
  • B.The component normal to the shock is reduced across it
  • C.The stagnation temperature is unchanged across it
  • D.The flow is deflected towards the shock surface

Answer: A

The tangential component passes through unchanged, since no pressure gradient acts along the shock. That fact, combined with the reduction of the normal component, is exactly what produces the deflection. The other three statements are all correct.
