The formula to find the speed of sound in air is as follows. Enter your air temp and choose your units. C gPr.
If the temperature is T C 20CT 293K T C 20 C T 293 K the speed of sound is v 343ms.
Taking g 14 gives a speed of sound of 343 ms 1. The speed of sound. Speed of sound the square root of the coefficient of adiabatic expansion the pressure of the gas the density of the medium. The formula to find the speed of sound in air is as follows.
