Nozzle Reaction - Smooth Bore
Estimates the reaction force at a smooth bore tip from tip diameter and nozzle pressure.
ℹVerify locally before acting. This tool is a planning and arithmetic aid, not a substitute for training, local SOPs, calibrated instruments, or scene assessment. Confirm critical values independently. Suite status: DRAFT - not yet department-approved for operational use.
When you'd use this: Deciding how many firefighters to put on a line - a 1-1/8" tip at 50 psi needs more hands than a 15/16" tip, and this quantifies the difference before the line is stretched.
Result
