Sonic velocity Calculator

The formula for calculating sonic velocity (the speed of sound) in a fluid depends on the properties of the fluid, such as its density (ρ) and bulk modulus (K). In a gas, the sonic velocity (vs) can be approximated using the equation:

Where:

  • = Sonic velocity (m/s)
  • = Bulk modulus of the fluid (Pa or N/m²)
  • = Density of the fluid (kg/m³)
