Bulk modulus - (SOM), It is the ratio of volumetric stress to volumetric strain. In Fluid mechanics it is the ratio of compressive stress to volumetric strain. Both sentences are same. And compressibility is the reciprocal of bulk modulus of elasticity.

Mach Number can be expressed with the density and the bulk modulus for elasticity as;
M = v (ρ/ E)1/2.
where
ρ = density of fluid (kg/m3, lb/ft3).
E = bulk modulus elasticity (N/m2 (Pa), lbf/in2 (psi)).
M = v (ρ/ E)1/2.
where
ρ = density of fluid (kg/m3, lb/ft3).
E = bulk modulus elasticity (N/m2 (Pa), lbf/in2 (psi)).

@All.
Don't you think that bulk modulus is the ratio of stress /strain? Please explain.
