Speed of Sound (ideal gas, heat capacitance)

`c_"Ideal" = sqrt( (( C_P / C_V )* R * "T" ) / "M" ) `

Enter a value for all fields

This equation computes the speed of sound through an ideal gas. The speed of sound in this case is a function of the temperature and the molar mass of the gas, as well as the constant pressure and constant volume heat capacitances of the gas.
