Bulk modulus elasticity

Overview

The bulk modulus ($K$) measures a fluid's resistance to compression. A high bulk modulus means the fluid is nearly incompressible.

Variables

Formula

$K = -V \frac{dP}{dV} = \rho \frac{dP}{d\rho}$

Notes

• Results are approximate and should be verified for critical applications
• Input values should be within reasonable engineering ranges
