QUESTION:
Air at 25 psia, 3208F, and Mach number Ma 5 0.7 flows through a duct. Calculate the velocity and the stag nation pressure, temperature, and density of air.
ANSWER:Step 1 of 4
Air flows through a duct at a specified state and Mach number. The velocity and the stagnation pressure, temperature, and density of the air are to be determined.
We assume that air is an ideal gas with constant specific heats at room temperature.
The properties of air are and
