Details of Kwinana Plume Plotter

This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Kwinana version of Plume Plotter.

Stacks and buildings

Building measurements are taken from [1] and [2].

The image below shows the layout of the stack and building modelled. North is at the top; colours and numbers indicate the height of the buildings and the stack:

Stack measurements

These are taken from [1] and [2]:

Stack location: -32.2102127,115.7791683.
Stack height: 87.5 m.
Stack diameter: 3 m.
Stack gas exit velocity: 18.3 m/s.
