Simple WinISD question

[Villainstone]

Hi guys I have a simple question about the ports in WinISD.
When I use multiple ports as opposed to just one obviously the program changes the port length. Now the new length that it tells me is that for each port of should I divide that new number in half for the length of each port? TYVM fellas.

It's the length of EACH port. You do NOT have to divide it in half.

What counts is the total cross sectional area. For example, two 2.5" diameter ports are roughly the same cross sectional area as a single 3.5" diameter port. You will find that the two 2.5" ports will be about the same length as one 3.5" port since the area is roughy equivalent.
