ABSTRACT:
A method is disclosed for determining bulk modulus of a liquid based on a pressure-volume-temperature relationship at constant volume corrected for changes in system volume due to elevated pressure and temperature. The apparatus used to determine bulk modulus comprises a pressure vessel in which the liquid to be tested is introduced, and from which all gases are removed. The vessel is placed in a constant temperature oven and the pressure is recorded. The method for determining bulk modulus and density requires calibration of the vessel volume changs due to pressure and temperature. The method for determining isothermal bulk modulus requires the solution of an empirical equation: ##EQU1##
