This software will calculate flow rate, friction loss and pump pressure for firefighters. You can plan for prescribed burns with greater accuracy, saving time and resources. During education and training, you can instantly demonstrate the effects of a larger hose size or higher nozzle pressure.

Hydrant and sprinkler color codes, flammable ranges for gases, inspection periods based on NFPA standards and fuel classes are all included.
