Appliance Loss Allowance

Looks up a configured manufacturer/agency appliance-loss value for the appliance type and flow. If no curve is configured for the combination, the tool returns "not calculated" rather than guessing.

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: Figuring out how much extra pressure to dial in at the panel for a specific in-line appliance - a wye, monitor, or deck gun - at a given flow, without digging through a manufacturer's chart.
