Formula for speed of sound c = 331 + 0.6 × ϑ

Ï‘ = temperature in degrees celsius.

At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s.

1 °C change of temperature is equal to 60 cm/s change of speed of sound.

The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary.

The ratio p_ / ρ is always constant on a high mountain, and even at "sea level". The static atmospheric pressure p_ and the density of air ρ go always together. The ratio stays constant.

When calculating the speed of sound forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height or elevation) only because of the changing temperature there!

Stream velocity does it have anything to do with discharge of stream or stream elevation?

Stream discharge physically depends on two factors: stream cross-sectional area and velocity. Area is composed of width and depth. Q (flow) = vel x width x depth. Stream elevation change, or how steep a stream is, will affect the velocity. Higher sloping streams (like those with few meanders) will travel faster than sinuous, snaking streams that have a lower elevation drop per length of stream.

Why velocity of sound depend upon nature of medium?

The velocity of sound depends on the nature of the medium because the properties of the medium, such as its density and elasticity, determine how quickly sound waves can travel through it. In general, sound travels faster in solids than in liquids, and faster in liquids than in gases, because solids have higher density and elasticity compared to liquids and gases. Additionally, the temperature of the medium can also affect the velocity of sound.


Give the effect of density on velocity of sound?

as density of medium increase velocity of sound decreases.
