Analysis of K-prime equations of state

In the present communication, we introduce a new K-prime equation of state (EoS), which can be used to understand the interior of the Earth. The newly developed EoS is found to yield similar results as given by Stacey K-prime EoS and Keane EoS, in reference to the seismological data. However, the zero pressure and infinite pressure extrapolation of higher pressure derivatives of bulk modulus are found different for different K-prime EoS.
