Bulk Modulus Elasticity

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

Bulk modulus elasticity (bulk modulus) 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.


\(K =    p  \frac {V_i}{ V_c}     \)


\(K \) or \(B \) = bulk modulus elasticity

\(p  \) = pressure

\(V_i\) = initial volume

\(V_c\) = change in volume

Solve for:

\(p =    K  \frac {V_c}{ V_i}     \)

\(V_i =  K  \frac {V_c}{ p}     \)

\(V_c =   \frac {p V_i}{ K}     \)
