kart and sonic velocity

Gas Sonic Velocity calculator, calculates the sonic velocity of a specified gas flowing in a pipe. Sonic velocity is also known as speed of sound. This is mainly the sound velocity of the internal substance in a pipe. This calculator is mainly targets process and chemical engineers whom may find it useful for quick check calculations.
The calculator has a small database that contain the following 51 gases and their specific heat ratio along with their molecular weights for quick reference
The calculator needs only the Temperature input to calculate the sonic velocity.
