The bulk modulus or elasticity is a measure of the resistance to compression of a substance. This article presents the bulk modulus for various liquids.

Bulk Modulus for Liquids
The bulk modulus for a liquid is defined as the ratio of a change in pressure to the relative change in volume. Common uses for the bulk modulus include:
- Calculation of the speed of sound for liquids, which useful for applications where pressure waves are important like dynamics modelling and surge analysis.
- Determination of the lag in response time for hydraulic systems.
Properties for various liquids at 1 atm and 20°C are shown in the table below.
