To introduce the data relative to the duct, it is subdivided in segments and for every segment the
user must insert:
Initial diameter,
Segment length,
Final diameter.
The convention, like previously explained, is to introduce the values of the segments from left to
right: in the previous case the first segment (and therefore the first line of the grid) will be that on
the left at contact with the atmosphere (or with the volume if is present). It is necessary however to
add a further length for every end with the atmosphere about the half of the diameter (0.5*D) to
keep account of the end effects (the part sketched in the figure submitting represents only the left
end).
