what is the equation for speed of sound. The speed of sound is a constant within a given gas and the value of the constant depends on the type of gas air pure oxygen carbon dioxide etc and the temperature of the gas. The formula to find the speed of sound in air is as follows.
1d It Shows The Wave Speed Equation And It I Could Use This Equation To Make Predictions Wave Equation Learning Targets Learning from www.pinterest.com
This powerful formula works pretty well in most solids liquids and gases. The specific acoustic impedance z of a medium is defined by pu so using the equations above. C_air 3313 x 1 T27315 ms You may think airs humidity would be a factor but this formula shows that is not the case.
Speed of sound the square root of the coefficient ratio of specific heats the pressure of the gas the density of the medium.
V 343 ms. Therefore for air at T K C F the speed of sound is v sound ms fts mihr. Pressure p 3kPa 3000 Pa. Using a data logger and microphones to measure the speed of sound For example two microphones are 34 m apart.
