We are able to start to fill a few of the info in, we are able to 1st include the quantity move fees for every on the branches, this is simple as its just the volume circulation level with the space which it serves. You are able to see on the chart I’ve filled that in.

It is because an extra branch now feeds the a few lesser branches making it possible for a number of the air to efficiently break away from the key movement and feed into these smaller branches.

If we consider the air travelling straight nevertheless first, we locate the velocity ratio to start with utilizing the system velocity out divided by velocity in. In this example the air out is 3.3m/s and also the air in is 4m/s which supplies us 0.eighty three
