We will start to fill a few of the data in, we will initial consist of the volume movement costs for each in the branches, this is a snap as its just the quantity move amount for the area which it serves. It is possible to see within the chart I’ve filled that in.
The final stage is to determine what resources are needed to finish the job depending on your prepared duct system.

At this intersection we draw a line to find the velocity and we could see that it falls inside the strains of 3 and 4m/s so we must estimate the value, In such a case it appears to more info be about 3.
