InfoWorks WS Pro allows you to carry out automatic lookup of roughness, pipe diameter, wave celerity and CO2 cost of material based on the value in the pipe Material field and some other field values.
- Colebrook White Roughness
- Hazen Williams Roughness
- Darcy Weisbach Roughness
- Effective Pipe Diameter
- Wave Celerity
- CO2 Cost of Material
For instructions on carrying out the lookup procedures, see the Setting Pipe Roughness, Setting Pipe Diameter, Setting Wave Celerity and Setting CO2 Cost of Material topics.
The list of pipe materials, and their associated lookup tables are maintained on the Pipe Materials dialog, which is accessed by choosing Pipe Materials from the Tools menu.
Roughness Lookup
See Setting Pipe Roughness for full details and instructions. The values in the built in roughness lookup tables come from WRc guidelines.
In order to use automated lookup, you must have the Material field of the pipes you want to adjust set to a type that is included in the lookup tables.
There are other roughness lookup tables (not used for automated lookup) provided with InfoWorks, each coming from a different source and based on different research. You need to use your own judgement as to which data is most appropriate.
Effective Diameter Lookup
The values in the effective diameter lookup table are calculated from water industry specifications using a simple algorithm. The Maximum External Diameter and the Minimum Wall Thickness are used to come up with an internal diameter.
Bear in mind that because of the values used the internal diameter calculated could be an over-estimate.
There is an additional Nominal Size Table provided with InfoWorks, with values coming from a different source and based on different research. You need to use your own judgement as to which data is most appropriate.
See Setting Pipe Diameter for more information and instructions.
Wave Celerity Lookup
See Setting Wave Celerity for full details and instructions.
In order to use automated lookup, you must have the Material field of the pipes you want to adjust set to a type that is included in the lookup tables.
CO2 Cost of Material Lookup
See Setting CO2 Cost of Material for full details and instructions.
In order to use automated lookup, you must have the Material and Diameter field of the pipes you want to adjust set to a type that is included in the lookup tables.
