A node can be a join point, tank, or demand pressure–referred to as End Pressure in the Node pane. Than click on Adjust Attributes of Selected Pipes button. To change the data of a group of pipes or to copy various attributes of the default pipe to each of the pipe select the group of pipes using the selecting tool. Note you can different component to any pipe such as fittings, valves, pump you can also open or close a pipe or reverse its direction. The pipe is characterized by its name, length, diameter, roughness (material) and finally by its starting and end elevation node. To add a pipe a pipe click on add pipes button from the drawing tool buttons. First we create the new fluid than we select the pipes that carry the new fluid. The density and viscosity of each fluid zone must be set by the user. Pipe Flow Expert will allow the user to design pipeline systems with up to 20 different fluid zones. Click on calculate gas data, a window will appear, then select the gas the working pressure and temperature, the program will generate the desnity and viscosity at the end click to add to the fluid list. And If the fluid you are using in the pipe system is one of the most common gases, the viscosity and density of the gas at various temperatures and pressures can be calculated. First we all know that the density and viscosity change with the change in temperature. For more information about adding a pipe material, see: Adding a Pipe Material to the Database section in Section: Creating a Pipe System. If the pipe material is not in the Choose new pipe material list, click the Add new material button to add the new material to the list. Select the pipe’s material from the Choose new pipe material list. This opens the Pipe diameter data screen A list of all the pipe materials available in the pipe database are displayed in the Choose new pipe material list. To draw in 3d view press on isometric mode. This section details the different features of the Pipe Flow Expert interface and we will provide detailed information about each features in the coming slides. 
These equations assume a constant fluid density & viscosity. Pipe Flow Expert uses the Darcy equation to calculate friction loss in a pipe. Note : Pipe Flow Expert uses the Colebrook equation to calculate friction factors.Value within this range, such that the mode PRV operation problems can be avoided byįinding the valve's pressure regulating rangeĪnd specifying the valve’s set pressure to a.
If the fluid doesn’t exist you can add the Next select the working fluid from fluid menu.Select the default pipe values such as pipe.Fittings and valves (regular and control).
