Wet barrel hydrants have a messy valve assembly at each port. Dry barrels are simple - water floods the barrel and exits any open port(s). I'm just trying to be sure of whether there is any unusually high loss in the barrel when flowing and while I'm at it, would like to verify the difference between one port flowing and two or three. We need 20 PSI at the discharge side of the port, so would like to include a fixed loss or just start the model at 23 or 24 psi or whatever is required to address the loss in the hydrant.

Just curious... Reverse engineering the water supply in the water main below?
