Flow Rate Determination

For sewage water, drinking water and storm water a comprehensive determination of the total flow in consideration of many different parameters is available. During the complete flow determination international standards are taken into account.

The flow rate determination for sewage water occurs corresponding to EN 12056 and DIN 1986. The program calculates the required volume flow according to several drainage facilities, type of building and type of pipe system. Alternatively, the flow rate can be determined with the help of population size and specific peak flow.

The calculation of storm water amounts also uses EN 12056 and DIN 1986. Statistical values for rainfall are already stored in the database. The calculation can be carried out for different types of drainage areas.

For drinking water, the peak flow is determined corresponding to DIN 1988 in consideration of the simultaneity of water extraction. The user chooses from default data of different types of building usages as well as drinking water extraction points.

Calculation of Total Head and Flow

The calculation of the pressure loss in unbranched pipe line systems is the main task of the second program function. The calculation can be effected using either of the models of COLEBROCK or HAZEN WILLIAMS.

Number and structure of available pipe systems can be provided by the user. The following are examples of the selection options:

Standard piping
Line system
Submersible pump system
Cooling system
Drinking water supply system
Closed circulation system
Parallel operation

There are data input fields for all values that are required for the calculation - geodetic head, tank pressure and head loss.

By clicking the calculation keys the user can determine the elements of every single line consisting of pipes, elbows, transitions, valves and other fittings. The resulting single losses and total loss of the respective line are calculated simultaneous.

The calculation is based on a freely expandable database with single elements. For the calculation of the pressure loss in valves and fittings different requirements can be set, for instance ζ or kv value or functional dependence on ζ(v) or Hv(Q).

Datasheet Generation

All input data and calculation results are summarized on a datasheet what ensures the documentation of the system dimensioning.
