Pipe roughness
The flow profile of the fluid is influenced by the roughness of the inner pipe wall.
The roughness is used for the calculation of the profile correction factor.
In most cases, the pipe roughness cannot be exactly determined and must therefore be
estimated.
For the roughness of some materials, see annex C.
• Enter the roughness for the selected pipe or lining material.
• Change the value according to the condition of the inner pipe wall.
• Press ENTER.
