Note that the minimum length of the tube is equal to the maximum head loss to be at least as great as the maximum head loss with some additional length to be able to reach the ports.
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. 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.
Finally, the length of the tube is determined using the Hagen-Poiseulle equation and the diameter of the tube found in the previous step.
