Fog Nozzle Flows & Pressures: Rated vs Actual, Reaction & Status
This lesson is part of the course
In this lesson
You work out how much six fixed-gallonage fog nozzles really flow when the nozzle pressure is off, estimate their reaction and flag the nozzles that fall below 90 % of their rated flow.
