Mechanical Engineering > GATE 2024 > Compressible Flow
Steady, compressible flow of air takes place through an adiabatic converging-diverging nozzle, as shown in the figure. For a particular value of pressure difference across the nozzle, a stationary normal shock wave forms in the diverging section of the nozzle. If E and F denote the flow conditions just upstream and downstream of the normal shock, respectively, which of the following statement(s) is/are TRUE?
A
Static pressure at E is lower than the static pressure at F
B
Density at E is lower than the density at F
C
Mach number at E is lower than the Mach number at F
D
Specific entropy at E is lower than the specific entropy at F

Correct : a,b
