Bulk Modulus

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Bulk Modulus is an essential tool for understanding Bulk Modulus in quantitative terms. Calculate K = -ΔP / (ΔV/V).

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = -1 × (dp ÷ vol_strain)
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
dp Change in Pressure Pa
vol_strain Volumetric Strain

Practical Calculation Example

Problem

Calculating the result when:

  • Change in Pressure = 85 Pa
  • Volumetric Strain = 55

Solution

Substituting into Eq 1.1:

Result = -1 × (85 ÷ 55)
