Baonza equation of state
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:
where is the isothermal bulk modulus, is the pressure derivative of the bulk modulus and relates the bulk modulus and its pressure derivative via:
