The velocity component tangential to an oblique shock is

  • A.Increased across the shock
  • B.Reduced to zero across the shock
  • C.Unchanged across the shock
  • D.Reduced across the shock

Answer: C

Applying the momentum equation in the direction along the shock, where no pressure difference acts, shows the tangential component to be preserved. Only the normal component is reduced. That combination is what turns the flow towards the shock surface and gives the deflection an oblique shock produces.
