Calculation

Explains the concept of the calculation dialog in Pipe and Duct Network Calculations.

General

Use the button Calculation to start detection of the pipe and duct network along with the automatically following calculation including dimensioning of pipes and ducts.

After calculating, the calculation dialog opens. The calculation dialog provides an overview of the pipe network. All systems, flow paths, section parts, components contained by the pipe or duct network and their calculation results are listed in tables. By clicking Edit... you may further specify settings for flow paths, section parts and components.

You can adjust the configuration in the Settings dialog, the specifications for the pipe or duct material used, the settings for the insulation and the technical data of the components at any time. Even if you make changes in the construction of the pipe or duct network or add or change components, this is not a problem. When detecting and calculating the pipe- or duct network, the calculation dialog always displays current calculation results.

Flow paths

Within the selected system, a flow path is the entire way from the initial component through built-in parts up to the ending component.

Section parts

Each flow path is divided into section parts. The first section part leads from the initial component up to the next t-piece or built-in part that features a change in nominal diameter or material. All following section parts lead from t-piece or built-in part up to the next t-piece or built-in part. The last section part leads from the last t-piece or built-in part up to the ending component.

Section parts are divided by the following components:

  • Branches
  • Transitions
  • Components for change of dimension or material
  • System-dividing components like pumps, hydraulic separator or heat exchanger.

Depending on the selected trade, there are other components that separate section parts.

Heating:

  • Pumps
  • Manifolds
  • Buffer storage
  • Hydraulic separator
  • Three-way valves
  • Heat exchanger

Potable Water:

  • Pumps
  • Manifolds

Waste Water:

  • Lifting station
  • Sometimes: bends, if they switch direction from vertical to horizontal and thereby impact pipe type.

Components

Each section part consists of individual components.
  • Initial and ending components
  • Pipes or ducts
  • Built-in parts
  • Fittings like t-pieces, branches, bends

Further functions

Depending on the selected trade, further functions for the calculation are available in the calculation dialog. You can view summarized calculation results, see notes and error reports regarding the calculation and label the pipe network. The function Visualization allows you to visualize different properties of the network in the drawing.

If you have created a single-line drawing, you can - provided you have a license - assign material from the 3D Pipework module to the pipes in the pipe network after the calculation. A three-dimensional pipe network is generated from the single-line pipe network. You can generate 3D lines for the entire network or for partial networks.
