Class description:

This will as handline focused class that will start with a update of the current on going Interior Stream Study at the ULFRSI, which is now in its final drafting stage. Followed by a discussion of the big four of handline attack package design:

Nozzle Design and implications: NP, Weight, Stream Type, Reaction Force, Stream Velocity, Selecting Target flow
Hose Construction and implication: Materials, Weaving, Construction Type, Inspection both annual and after every use.
Hose size and implication: Target flows and tube velocity the things you need to know before buying hose hydraulically.
Pump Panel Outlet implications: Design, errors, plumbing, pick up placement, foam loop complications and flow meters.
