Title: Record hydrant flow pressures.
Course: Firefighting II (15152-II) > Section: Managing Hydrant Flow and Operability

Recording flow pressures should include periodically testing a location by

- using and reading a pitot tube
- using the discharge equation (discharge = 1/2 x outlet diameter)
- using water flow tables
- diagnosing the cause of an obstruction in the hydrant flow, if any.

Process/Skill Questions:

- What are hydrant flow codes, and how are they assigned?
- What are three conditions that may reduce hydrant effectiveness?
- What are the differences between wet-barrel and dry-barrel hydrants? Where might these hydrants be found?
