Bulk Modulus

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Bulk modulus ( \(B\) or \(K\) ) (also known as bulk modulus elasticity) is the elastic relationship between an applied pressure that acts to change the volume of the substance and the ability of a substance to withstand changes in volume when under compression.

Bulk Modulus Formula

\(K =    p  \frac {V_i}{ V_c}     \)

Where:

\(K \) = bulk modulus

\(V_c\) = change in volume

\(V_i\) = initial volume

\(p  \) = pressure

Solve for:

\(p =    K  \frac {V_c}{ V_i}     \)

\(V_i =  K  \frac {V_c}{ p}     \)

\(V_c =   \frac {p V_i}{ K}     \)
