REMARKS ON THE KUMAR ISOTHERMAL EQUATION

A comparison is made between an equation for room-temperature isotherm s recently proposed by Kumar, and a universal system-independent equat ion of state proposed some years ago by Prieto and Renero. This compar ison is made using both equations to obtain room-temperature isotherms for Cu, Pd, K and Mo. It is also shown that by the use of suitable sc aling factors for the variables involved in Kumar's equation, it can b e expressed in universal system-independent form.
