Gas Sonic Velocity Calculator

This tool calculates sonic velocity of a gas in a pipe.

Gas Sonic Velocity calculator calculates the sonic velocity of a specified gas flowing in a pipe. The sonic velocity or the speed of sound is affected by the gas in a pipe depending on the physical properties of it. This is mainly the sound velocity of the internal substance in a pipe. The velocity gives you a clear indication about process and pipe material design for process and chemical engineers. They will find it useful for quick check calculations. It uses a database of 51 well known gases and their specific heat ratios along with their molecular weights for quick reference. These include air, ammonia, many inert gases, and common gases used in pipeline flow. Only inputs required for calculating the sonic velocity is the temperature.

The temperature input can be in degrees Celsius, Fahrenheit, Rankine or Kelvin. It is possible to choose "Other" from the selection box and enter your own specific heats ratio. Another alternative is to enter the Specific heat ratio at constant volume and Specific heat ratio at constant pressure. The calculated velocity value can be displayed in units of your choice. These could be meters per seconds (m/s), feet per second (ft/s), inches per second (inch/s), kilometer per hour (km/h) or miles per hour (mile/h). Versions of the calculator are available for smartphones of iOS as well as Android operating systems. Windows desktop version is available free. This is a good and handy tool.

Calculate 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. The Temperature can be specified in
Degrees Celsius ('C)
Degrees Fahrenheit ('F)
Degrees Rankine ('R)
Degrees Kelvin ('K)
You can choose "Other" from the selection box and enter your own Specific heats ratio or alternatively enter the Specific heat ratio at constant volume and Specific heat ratio at constant pressure.
The calculated sonic velocity in pipe (speed of sound) output is displayed in 5 different units:
meters per seconds (m/s)
feets per second (ft/s)
inches per second (inch/s)
kilometer per hour (km/h)
miles per hour (mile/h)
