Calculation of the stack height according to TA Luft 1986/2002 with regard to rugged terrain according to VDI 3781 Part 2

---

P&K 3781 is organized in two program sections independent from each other. In one section one can calculate the stack height according to TA Luft, including an additional development and vegetation. In the other section the height correction with regard to rugged terrain according to VDI 3781 part 2 can be calculated.

Project for both parts can be managed under the menu File. Inputs forms and reports are available under the menu TA Luft and VDI 3781

To determine a stack height according to TA Luft, one can enter the material data in TA Luft/List of the pollutants and the other source data into TA Luft/Stack height according to TA Luft Nomogram. To commit the calculation of the stack height, one has to press the button Update. Further control information is available in TA Luft/List of the pollutants. The data can be visualize under the menu TA Luft/Report.

To determine a stack height correction according VDI 3781, one can begin with entering the terrain profile into the menu VDI 3781/Terrain profile. Next one can enter data and determine the schematics under the menu VDI 3781/Parameter for profile adaption. Under the menu VDI 3781/Correction of the stack height one can (after entering more information and pressing the button Update) view the results. Input data and results can be visualize under VDI 3781/Report. Also, an illustration of the schematics can be viewed under VDI 3781/Graphic.
