Bulk Modulus Equation

Reference from the original Physics I textbook.

Bulk Modulus Equation

$B = - \frac{Δ p}{Δ V / V}$

$B = Bulk Modulus (Pa)$
$Δ p = Pressure (Pa)$
$Δ V = Change in Volume (m^{3})$
$V = Initial Volume (m^{3})$

Bulk modulus
Bulk modulus measures resistance to compression through pressure change divided by fractional volume decrease. A larger modulus means a smaller volume change for the same pressure increase within the model’s range. For example, a liquid with a high bulk modulus can often be approximated as incompressible in modest-pressure flow problems.
