AB - A fast flash calculation of the Rachford-Rice equation is very much needed in  many engineering applications, especially in multi-component mixtures. This  paper suggests a direct and hands-on calculation by a pocket calculator or  a Chinese abacus. The calculation is based on an ancient Chinese  mathematics called as He Chengtian average. An example is given to show the  simplicity and effectiveness of the ancient Chinese algorithm.
