Aerospace Engineering > GATE 2022 > Compressible Flow
In a converging duct, area and velocity at section P are 1 m2 and 15 m/s, respectively. The temperature of the fluid is 300 K. Airflow through the nozzle can be assumed to be inviscid and isothermal. The characteristic gas constant is 287 J/(kg-K) and the ratio of specific heats is 1.4 for air. To ensure that the airflow remains incompressible (Mach number, M ≤ 0.3) in the duct, the minimum area required at section Q is _______ m2. (rounded off to two decimal places)
Correct : 0.14 to 0.15
