Solution of the problem of finding the balance of a gaseous mixture is rather frequently encountered both by chemical engineers and chemists dealing with rocket propellant research. This problem is defined by a nonlinear system of algebraic equations the computation of which is a lengthy and tiresome numerical job. The numerical solution of such a problem by desk computing machine requires several days of work for each separate solution and is, of course, subject to human errors made by the calculator himself. It, therefore, became apparent that the use of digital computing machine was indispensable. So far, this problem has been tackled by high memory capacity computing machines, but since many of the engineers dealing with it cannot have such machines made readily available, the author believes that they should be given a method of solving the problem by employing the optimum efficiency of low-capacity digital computing machines. A complete solution is given here for all components of the solution, this being the most complicated part of the problem. No numerical difficulties should be experienced by using the calculated components for plotting the i, s T-diagrams.
