A technique for solving hydraulic network flow distribution problems using a standard analog computer is presented. This method can be applied to networks which include various hydraulic components such as valves and pumps. The indirect analog simulation proposed has the advantage that only a standard analog computer is needed and not specially constructed direct analog devices. In addition, analog simulation is particularly useful for carrying out parametric studies and, therefore, is a valuable design tool. Examples are presented which illustrate the technique used for solving the flow distribution problems. Also, the examples are used to compare the analog solutions to these obtained by a conventional Hardy-Cross analysis and the analog solutions are shown to be very accurate.
