Continuing that case, the Mach number normal to the shock downstream is nearest to

  • A.1.500
  • B.0.845
  • C.0.701
  • D.0.577

Answer: C

The normal component behaves exactly as it would through a normal shock at \( M = 1.5 \), so it emerges at \( 0.701 \). Note that this is not the downstream Mach number: the tangential component is unchanged, and the resultant downstream Mach number is obtained by dividing 0.701 by the sine of the shock angle less the deflection.
