h. MACH number is a decimal number (M) representing the true airspeed (TAS) relationship to the local speed of sound (e.g., TAS 75 percent (0.75 M) of the speed of sound where 100 percent of the speed of sound is represented as MACH 1 (1.0 M)). The local speed of sound varies with changes in …

The speed of sound in a gas in inversely proportional to the square root of the molecular weight of the gas through which the sound is passing the speed of sound will be greater in moist air. This is because the molecular weight of water is less than that of dry air. At 20oC 100 kPa and 0% humidity the speed of sound is 343.4 m/s.

The speed of sound is 340 m/s. A plane flies horizontally at an altitude of 10 000 m and a speed of 400 m/s. When an observer on the ground hears the sonic boom the horizontal distance from the point on its path directly above the observer to the plane is: (Shock Wave) a. 5 800 m b. 6 200 m c. 8 400 m d. 12 000 m e. 16 000 m

The speed of sound in air depends on a number of things: (ask class) air pressure, altitude (density), air composition (humidity), temperature. (Ask how each one could affect the speed of sound). The temperature dependence of the speed of sound is the most noticeable.

1. In the earth’s atmosphere the speed of sound is a function of the altitude. The figure above consisting of 3 line segments shows the speed of sound in m/sec. as a function of altitude, a in meters. The graph is not drawn to scale. What is the average speed of sound in m/sec. on the interval [0, 32,000]?
