1.	Consider a flow with 0.5M. Now, as area decreases, velocity of the flow inside convergent section _____________(a) increases(b) decreases(c) reduces by half always(d) velocity is independent of areaI had been asked this question in a national level competition.The query is from Propulsion in division Propulsion and Fuel System Integration of Aircraft Design
Answer» Correct OPTION is (a) increases Easy explanation: Given, MACH NUMBER = 0.5. The flow is in subsonic speed region. For subsonic speed, as AREA decreases the flow velocity will increase for CONVERGENT nozzle.
