Question 53
AENAT2 marksNeeds review
In a converging duct, area and velocity at section P are 1 m
and 15 m/s, respectively. The temperature of the fluid is 300 K.Air flow through the nozzle can be assumed to be inviscid and isothermal. Characteristic gas constant is 287 J/(kg-K) and ratio of specific heats is 1.4 for air.
To ensure that the air flow remains incompressible (Mach number,
) in the duct, the minimum area required at section Q is ____ m
(rounded off to two decimal places).
