Description: The method of treating a set of isothermally measured pressures Ṕ, Ṕ, Ṕ, ... , Pr, for a Burnett experiment, consists of expressing the compressibility factor isotherm of the gas in terms of a function of either P or p [rho] and evaluating the volume ratio, Np=0, and the constants in the function by least squares solution. This report gives the method of least squares as applied to the fundamental equation for the Burnett experiment, taking into consideration the change in Np=0 with pressure. Formulas are given for evaluating the standard deviation of a single Pr, the standard deviation of each of the constants evaluated, and the standard deviation of the compressibility factor.
