Normalized air · cycle rate · demand
Pneumatic air-demand budget
Inputs
User-entered normalized free-air demand per one completed device cycle; cylinder geometry and pressure are not derived.
User-entered repeated cycles per minute for each stated active device.
Positive whole count of devices sharing the same declared demand record.
Percent greater than 0 through 100 used only to scale stated repeated demand.
User-entered normalized reference flow for literal ratio arithmetic only; it is not a capacity rating or selection input.

Method
Formula, when it applies, and when it does not
Aggregate normalized air demand per cycle, cycle rate, active-device count, and duty fraction into average air demand and a reference-flow ratio.
nactive = ncycle·z·D/100; Qavg = qcycle·nactive; ratio = Qavg/Qref
When
- User-entered normalized air per cycle
- Declared repeated cycle rate
- Equal stated device demand
- Declared duty fraction
Don’t
- This aggregates only user-declared normalized air demand, cycle rate, active-device count, and active-time fraction. It does not derive cylinder consumption; select or size a compressor, FRL, tubing, valve, or vacuum generator; model pressure-drop networks, air storage, leaks, duty transients, compressor curves, air quality, capacity, safety, suitability, or approval.
