Cascade Nozzle Discharge & Friction Loss Slide Calculator

The Cascade Nozzle Discharge and Friction Loss Slide Calculator provides fast field reference calculations for wildland and structural hose operations. Its two-sided design covers both English and metric measurements without requiring batteries or electronic equipment.
Features
- Calculates nozzle discharge from nozzle pressure and bore size
- Calculates friction loss for single and siamese hose lines
- English measurements on one side and metric measurements on the reverse
- Supports nozzle bores as small as 3/16 in.
- Supports flow calculations beginning at 5 GPM
- Durable mechanical slide format for apparatus, station or field use
