QUESTION:
Determine the speed of sound in air at (a) 300 K and (b) 800 K. Also determine the Mach number of an aircraft moving in air at a velocity of for both cases.
ANSWER:
Step 1 of 3
The Mach number of an aircraft and the speed of sound in air are to be determined at two specified temperatures.
We assume that Air is an ideal gas with constant specific heats at room temperature.
The gas constant of air is . Its specific heat ratio at room temperature is .
