# Color Coding Dialog

This dialog allows you to color-code pipes based on multiple value ranges for flow, pressure, or velocity. To display the Color Coding Dialog: ▪Select the Tools | Color Coding menu item. When a model has been solved, you can then color-code all pipes in the model based on flow rate, pressure, or velocity as shown in Figure 1. You can also choose the flow, pressure, or velocity units applicable to your modelling case or color coding criteria (Figure 2). Figure 1: Color Coding Form - Default. Figure 2 shows how the color coding function has been set to color-grade the pipes based on different flow rate conditions (0.2 m3/h in black, 2 m3/h in maroon, 5 m3/h in red and 10 m3/h in aqua). Once you have set all your conditions, select the "Refresh Flowsheet" button to apply the color coding conditions. You will then see the pipes on the flowsheet have been color graded based on the criteria defined in Figure 2. Figure 2: Color Coding set to grade pipe color based on flow rate. Notes: 1. You can use the down arrow-key to create a new entry or select the green "plus" button on the bottom left of the "Color Coding" dialog to create a new entry field for your design condition. 2. Select the red "minus" button on the bottom left of the "Color Coding" dialog to delete an existing entry for your design condition. Related Information It can be helpful to increase the "draw thickness" for all pipes in the network. This gives the color coding much more visual impact. The quickest method of increasing pipe "draw thickness" is to: ▪Select the 'Edit | Select | Select Pipes' menu item. ▪While all pipes on the flowsheet are highlighted, select the INPUT tab of the Data Palette and set "draw thickness" to 3. All pipes will now appear thicker on the flowsheet. Click anywhere on the flowsheet to remove the pipe selection. Figure 3 below gives an overview of pipe color coding, in this case based on flow.
