From your rough drawing we measure out the size of every duct area and enter this in to the chart.
But, When you've got a short while ago replaced the lover motor or you would like to re-stability the airflow of the HVAC system, you’ll should measure the airflow of existing diffusers. No damper adjustment is required at this stage. Just measure and history the airflow.

65 pa per meter. So incorporate this figure to the chart. As we’re using the equivalent pressure fall strategy we could use this stress fall for every one of the duct lengths so fill People in way too.
