Phase 2 · Tool 10 of 77
Hose Friction Loss by Line
Totals friction loss, elevation effect, and appliance loss across up to 4 segments of a single line. Leave a segment's flow blank to skip it.
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: A multi-segment lay - say 300 ft of 3" supply reduced into 100 ft of 1.75" attack line - total the combined loss across both segments plus elevation and appliances in one pass, instead of running the single-segment tool twice.
Result
Enter at least one segment and press Calculate.
