Fixtures are organized into two occupancy groups operating in non-overlapping time windows (Section 5). Load values are public-use figures per Table E103.3(2). Group A — Daytime occupancy (incl. brewery operations) Fixture (public) WSFU ea. Qty Subtotal WSFU Water closet, flush tank 5 2 10 Lavatory 2 2 4 Kitchen / break sink (offset by brewery fill) 4 1 4 Group A total 18 WSFU Group B — Evening occupancy Fixture (public) WSFU ea. Qty Subtotal WSFU Water closet, flush tank 5 2 10 Lavatory 2 2 4 Service / mop sink 3 1 3 Group B total 17 WSFU An exterior hose bibb serves maintenance use only, operated outside occupied restroom peaks; it is non-coincident with the interior peak and not additive. There is no simultaneous irrigation demand. 5. Demand Analysis — Non-Coincident Use Fixture units are converted to a probable peak demand via Hunter's curve, Table E103.3(3), for a flush-tank system. Demand basis Total WSFU Peak demand Design — non-coincident, governing group (Group A) 18 18.8 gpm Basis of the non-coincident demand. Group A (daytime, including brewery operations) and Group B (evening) operate in separate, non-overlapping time windows. Simultaneous use of both groups is not possible: the facility does not brew during events, so an evening event cannot coincide with daytime brewery / kitchen demand. The service therefore never carries the two groups' combined load — the peak instantaneous demand is that of the single larger group, Group A at 18 WSFU → 18.8 gpm, not the arithmetic sum. Within Group A, the ~45-minute brewery fill occurs while the kitchen is offline and directly offsets the kitchen demand (Section 4), so it is not additive. This non-coincident basis is applied in addition to the simultaneity probability already embedded in Hunter's curve. 6. Service Capacity — Velocity Check Velocity governs the 1" service and is independent of available pressure: V = 0.4085 × Q ÷ d², d = 1.025 in. Demand basis Flow Velocity in 1" service Design — non-coincident 18.8 gpm 7.31 ft/s — WITHIN 8 ft/s ✓ Simultaneous A + B (precluded — reference) 24.9 gpm 9.68 ft/s — over 8 ft/s At the design (non-coincident) demand the service operates at 7.31 ft/s — 91% of its velocity ceiling, within limits. The simultaneous condition, precluded by the operating configuration, is shown for reference only. 7. Pressure Balance & Residual Pressure Per IPC Appendix E, source-to-building losses at the 18.8 gpm design demand are subtracted from available pressure to confirm adequate residual pressure remains.
