A method of selecting devices for use in a fluid pipeline network, wherein items of data concerning devices are stored in a pipe database, a pipe joint database and a valve database, and calculating equations for use in computation are also stored. Devices are temporarily selected by using the stored device data, and then computation is performed by using the stored calculating equations, thereby allowing device selection to be made easily. In addition, a block diagram of the fluid pipeline network can be made easily.

1. A method of selecting devices for use in a fluid pipeline network, comprising the steps of: making a circuit configuration of the fluid pipeline network by connecting together sections between a fluid source, inlet portions, branch points and outlet portions with section devices; giving a pressure at the fluid source and a flow rate at each outlet portion; and adjusting a pressure loss in each section between the fluid source and an inlet or outlet portion to a desired value of allowable pressure loss; wherein items of data concerning pipes, pipe joints and valves are stored in a pipe database, a pipe joint data base and a valve database, respectively, and calculating equations for use in computation are also stored, and wherein section devices, comprising said pipes, pipe joints and valves, are selected from the pipe database, the pipe joint database and the valve database, respectively, and pressure at the branch points and the outlet portions are computed with respect to the fluid pipeline network for which the section devices have been selected, by using the stored calculating equations. 2. A method of selecting devices for use in a fluid pipeline network according to claim 1, wherein after entry of the value of allowable pressure loss, the pressure at the fluid source and the flow rate at each of the inlet and outlet portions, all sections of the fluid pipeline network are subjected to computation using a node analysis method to judge whether or not there is a section that does not satisfy a condition of allowable pressure loss, and if there is such a section, an inlet/outlet flow rate change or a section device change is made with respect to said section, and then a judgment as to whether or not there is a section that does not satisfy the condition of allowable pressure loss is made again by computation using the node analysis method wherein the inlet/outlet flow rate change or the section device change and the computation are repeated until there is no section that does not satisfy the condition of allowable pressure loss. 3. A method of selecting devices for use in a fluid pipeline network according to claim 2, wherein node positions and branch positions, which are arranged in a grid pattern, are displayed on a screen, and inlet portions, branch points and outlet portions are selected from the node positions, and further, sections to which section devices are to be connected are selected from the branch positions and the node positions to make a circuit configuration. 4. A method of selecting devices for use in a fluid pipeline network according to claim 2, wherein node positions and branch positions, which are arranged in a grid pattern, are displayed on a screen, and inlet portions, branch points and outlet portions are selected from the node positions, and further, sections to which section devices are to be connected are selected from the branch positions and the node positions to make a circuit configuration, and as a result of the computation using the node analysis method, a pressure is displayed at each branch point, and a pressure and a flow rate are displayed at each of the inlet and outlet portions. 5. A method of selecting devices for use in a fluid pipeline network according to claim 1, wherein node positions and branch positions, which are arranged in a grid pattern, are displayed on a screen, and inlet portions, branch points and outlet portions are selected from the node positions, and further, sections to which section devices are to be connected are selected from the branch positions and the node positions to make a circuit configuration.
