## Main Question or Discussion Point

I am attempting to calculate the force (in KgF) of a water pump + nozzle system. I have the pump curve (head vs. flow rate) for the pump, the diameter of the connection hose (2 inches) and the nozzle diameter (1 inch). The connection hose between the pump and nozzle is very short (approx 10 cm). How do I calculate the possible forces created by this system by tuning the flow rate output from the pump? Thanks!

Example point on the pump curve: 20 psi at 180 gallons per minute.
