Aerospace Engineering > GATE 2022 > Compressible Flow
A convergent nozzle fed from a constant pressure, constant temperature reservoir, is discharging air to the atmosphere at 1 bar (absolute) with choked flow at the exit (marked as Q). Flow through the nozzle can be assumed to be isentropic.
If the exit area of the nozzle is increased while all the reservoir parameters and ambient conditions remain the same, then at steady-state _______.
A
the nozzle will remain choked
B
the nozzle will be un-choked
C
the Mach number at section P will increase
D
the Mach number at section P will decrease

Correct : a,c
