Bulk Modulus Modules

Calculate gas and liquid speed of sound and Mach number.

The Mach number is the ratio of the flow velocity to the speed of sound. It applies to either a moving fluid or to a moving object passing through stationary fluid. For a Mach number greater than one, the flow is supersonic. For a Mach number less than one, the flow is subsonic.

For an ideal gas, the speed of sound or sonic velocity can be calculated from the gas temperature, gas specific heat ratio and the gas specific gravity. For liquids the speed of sound can be calculated from the liquid bulk modulus and the liquid density.

Calculate the velocity of sound in a solid.

The speed of sound in a solid is calculated from the solid density and bulk modulus.

`a = √(K / ρ) `

where :

a = speed of sound
K = bulk modulus
ρ = density

The bulk modulus can be calculated from the elastic modulus and Poisson's ratio, or from the speed of sound in the solid.

`K = a^2 ρ `
`K = E / (3 (1 - 2 γ )) `

where :

E = elastic modulus
γ = Poisson ratio

Fluid density and specific gravity data.

For gases, the specific gravity is generally measured relative to air. For liquids, the specific gravity is generally measured relative to water.
