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=γB0B0′′[(1+B0′′(1γ−1)ln(V0V))1/(1−γ)−1]

where B0 is the isothermal bulk modulus, B0′′ is the pressure derivative of the bulk modulus and γ relates the bulk modulus and its pressure derivative via:

B=B0(1+B0′′B0P)γ
