How Can Bernoulli's Principle be Related to Fire Hoses

[Chairliftop]

Hello everybody:

I am trying to test, using Bernoulli's Principle, when firehoses are most effective.

I know this is extremely broad, but does anyone have any ideas for independent variables? I am thinking about the the width of the end piece of the nozzle...

Any help/guidance would be greatly appreciated.

Thank you in advance!

Ok; so what determines that?
