Result

Note — Inverse sizing solves riser-tube diameter and gate area so the target fill flow is met at the chosen velocities; Reynolds is checked.

Note — Typical LPDC gate velocity: 0.3–1.0 m/s (slow filling).

Note — With N cavities the riser tube carries the total flow; each cavity gate area is total / N (balanced runner).
