The tube diameter is then selected based on the diameter required for laminar flow and the diameter required for head loss. The largest of the two is chosen. Note that the maximum diameter is not compared because this was already taken into account for the minimum diameters by using Q.FcmTubeMax. From there the inner diameter of the FCM tube is found by comparing the minimum diameter to the available diameters. The diameter for the flow control module is designated as ID.FcmTube.
