SUMMARY

The bulk modulus of a liquid is defined as the inverse of compressibility. For liquids, the formula is expressed as K = -V (dP/dV), where K is the bulk modulus, V is the volume, dP is the change in pressure, and dV is the change in volume. This formula applies universally to all liquids, not just water. Understanding this concept is essential for projects involving fluid dynamics, such as water hammer analysis.

I am doing a project on water hammer. I need the formula for the bulk modulus of a liquid not just for water. Can anyone provide me with the formula?
