Baonza, et al formulated an equation based on a linear bulk modulus called the Baonza equation of state[1]. It has a simple analytical form but also gives similar accuracy to the Rose-Vinet (Universal) equation of state. The equation of state is:

p=\frac{\gamma B_0}{B_0'}\left[\left(1+B_0'\left(\frac{1}{\gamma}-1\right)ln\left(\frac{V_0}{V}\right)\right)^{1/(1-\gamma)}-1\right]

where B_0 is the isothermal bulk modulus, B_0' is the pressure derivative of the bulk modulus and \gamma relates the bulk modulus and its pressure derivative via:

B=B_0\left(1+\frac{B_0'}{B_0}P\right)^{\gamma}
