Test: Flow of Compressible Fluids - 2 - Question 3

Consider the curves in the sketch shown below  indicates normal shock)

Out of these curves, those which are not correctly drawn will include

Detailed Solution for Test: Flow of Compressible Fluids - 2 - Question 3

Since shock will not be experienced at converging portion hence plot (2) is wrong. During the shock flow velocity decreases and pressure rise takes place but in figure (3) pressure in decreasing hence it is wrong.
