This report develops the relationships needed to analyze steady flow of a solid-liquid slurry in a network of pipes. The relationships include the basic slurry flow equations for a pipe network and an additional set of equations for continuity of the solid phase. Special relationships for solids injectors and separators are developed. The analysis of a slurry transport system composed of several pipes is complex and requires repeated solutions of nonlinear, simultaneous, algebraic equations. Good design of a slurry transport system requires the reliable analysis of the system operating under a variety of conditions. The only practical means of carrying out these analyses is with the aid of a computer simulation. A computer program which utilizes the theoretical expressions was developed and tested and is presented in this report. Detailed data coding instructions are given and the use of the program is illustrated by two examples of relatively complex slurry hydrotransport systems. The computer program was designed to be flexible and reliable and incorporates many features available using programs developed for clear-liquid piping systems. Some of the principal features include: any pipe system configuration can be analyzed; pumps can be included and described in several ways; check valves and restricted lines can be simulated; both English and S.I. units can be used; and solids injectors and separators can be simulated. The computer program is easily used and is a valuable design aid for slurry hydrotransport systems.
