QUESTION: 1

Solution:
QUESTION: 2

### Across a normal shock

Solution: Hence during the normal shock wave static pressure and static temperature rise takes place.

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

Solution:

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.

QUESTION: 4

Consider the following statements:
