The speed of sound varies depending on the temperature, pressure, and density of the medium through which the sound waves travel. For dry air at sea level at 68° F, the speed of sound is 767 miles per hour, or 1235 km/h


The approximate speed of sound in dry (0% humidity) air, ... This equation is derived from the first two terms of the ...


At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: ...


Calculation formulas for velocity of sound - sonic velocity - in gases, fluids or solids.


The speed of sound in an ideal gas is given by the relationship ... 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air: ...


v is the speed of sound and T is the temperature of the air. One thing to keep in mind is that this formula finds the average speed of sound for any given ...


This calculation is usually accurate enough for dry air, but for great precision one must examine the more general relationship for sound speed in gases.


Air is a gas, and a very important property of any gas is the speed of sound through the gas. Why are we interested in the speed of sound? The speed of " sound" ...


This is a formula that is confusing until you start to look at the units. Wavelength is a measurement of length, and has units in meters (m). Frequency is a measure ...


Air is a gas, and a very important property of any gas is the speed of sound through the gas ... The equation given above was derived for a calorically perfect gas.
