Steady, compressible flow of air takes place through an adiabatic converging-diverging 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 is TRUE?
- 1The specific entropy at E is lower than the specific entropy at F✓
- 2The density at E is higher than the density at F
- 3The static pressure at E is higher than the static pressure at F
- 4The Mach number at E is lower than the Mach number at F
Correct answer
The specific entropy at E is lower than the specific entropy at F
