Fog Nozzle Flow

Reads the nozzle's rated flow/pressure point directly, and only approximates away from that point within a bounded range. The manufacturer's actual curve always governs - this refuses to extrapolate beyond 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: Field conditions push pump pressure away from a fog nozzle's rated operating point (a long lay, significant elevation) - estimate the resulting flow change without needing a full new curve from the manufacturer.
