E = density*dp/change in density. From bernoulli's equation if the order of pressure is same as the order of dynamic pressure then dp=density*velocity square/2. By substituting this in equation for bulk modulus we get. Change in density/density=1/2* (mach. No) square. Where mach number Ma=v/a.
9 velocity of fluid flow/velocity of sound in medium. If change in density/density is < 0. 05 we say fluid is incompressible. So Ma, 0. 33 for the flow to be compressible.

What is mach number?

Bulk modulus is equal to the reciprocal of compressibility.
And Mach number is depends upon the compressibility.
Therefore to determine Mach number bulk modulus is required.

How will you determine a bulk modules by using mach numbers?
