Speed of Sound in Dry Air

The speed of sound in dry air at 20°C is 343.5 m s, and the frequency of the sound from the middle C note on a piano is 261.6 s (according to the American standard pitch scale). Calculate the wavelength of this sound and the time it will take to travel 30.0 m across a concert hall. [Pg.164]

These values were calculated from the equation of state for dry air (average molecular weight 28.96) treated as a real gas. Values refer to standard atmospheric pressure. The speed of sound varies only slightly with pressure at two atmospheres and -100 °C the value decreases by 0.16%, while at two atmospheres and 80 °C the speed increases by 0.05%. For additional values, see the table in Section 6 labeled Thermophysical Properties of Air. ... [Pg.2310]
