Cascade Friction Loss Calculator

Our nozzle discharge/friction loss Slide Calculator is a useful tool in determining flows through nozzle sizes as small as 3/16” at practical fire nozzle pressures. It can also be used to calculate friction loss in hose lines of various sizes through a flow range as small as 5 GPM. The two-sided design displays both English and Metric measurements. This calculator is recommended for wildland firefighting.
