Figure 58: Pipe Page From Nominal Entry
This page is used for the manual entry of pipe parameters. If the lookup function in Site>Lookup was used, nominal values
for Pipe OD, Pipe Wall [Thickness], and Roughness are automatically entered. If the actual values of the pipe differ from the
ones automatically entered, go back to Site>Lookup and select Manual Dimension Entry to enable entry of non-standard
parameters. The choice of Manual Dimension Entry will unlock the Pipe Material, Pipe OD, and Pipe Wall [Thickness] inputs as
shown in Figure 59 .

Pipe Material
When a pipe material is chosen from the Pipe Material list, a nominal value for speed of sound in that material and the pipe
roughness are automatically loaded. If the actual sound speed is known for the application piping system and that value
varies from the nominal value loaded, the value can be revised.
