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.

Euler number = pressure force to inertia force.
Reynold no= inertia force to viscous force.
Froude no=inertia force to external force.
Reynold no= inertia force to viscous force.
Froude no=inertia force to external force.

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 NO OR CAUCHY'S NO IS the ratio of inertia force to elastic force & also ratio of speed of flow(v) to velocity of sound(c) so,
c= √K/row(p).
k is bulk modulus.
c= √K/row(p).
k is bulk modulus.

Bulk modulus is proportional to pressure. So I think Euler's number is the correct answer. It is the ratio of inertia force and pressure force.

Bulk modulus " the measure of a fluid's resistance to compression "of a hydraulic fluid in position, response time, and stability are critical.

Mach Number (M).
M<1 = subsonic flow.
M=1 = sonic flow.
M is 1 to 6 = supersonic flow.
M more than 6 = hypersonic flow.
Mach Number Or Cauchy's Number = Inertia force to elastic force.
Euler number = Inertia force to Pressure force.
Weber's Number = inertia force to surface tension force.
Froude's number = inertia to gravity force.
Reynold's number = inertia to viscous.
M<1 = subsonic flow.
M=1 = sonic flow.
M is 1 to 6 = supersonic flow.
M more than 6 = hypersonic flow.
Mach Number Or Cauchy's Number = Inertia force to elastic force.
Euler number = Inertia force to Pressure force.
Weber's Number = inertia force to surface tension force.

Reynold's number = inertia to viscous.
