Document Summary

Large values for the bulk modulus indicate that the fluid is relative incompressible, meaning it takes a large pressure change to create a small change in volume. As liquids are compressed the bulk modulus increases. Although the bulk modulus is most prevalent when dealing with liquids, it can be used for gases too. When gases are compressed, the relationship between pressure and density depends on the nature of the process. If the compression or expansion is frictionless and no heat is exchanged with the surrou(cid:374)di(cid:374)gs it (cid:373)ea(cid:374)s, it"s isentropic. K is the ratio of the specific heat at a constant pressure. The value of the bulk modulus depends on the type of process involved. In both cases the bulk modulus varies directly with pressure. The velocity at which small disturbances propagate in a fluid is called the speed of sound. The velocity at which small disturbances propagate is called the acoustic velocity or speed of sound.
