About the items:
1. Discrete standard sizes – Flow (6 levels) and diameter (12 dash sizes) are stepwise, for quick lookup rather than continuous calculation.
2. Broad velocity range – Covers 0.6–14 m/s (2–30 ft/s) with fine 0.5 m/s steps, including high‑speed zones.
3. Dual units – All parameters shown in both metric (L/min, mm, m/s) and imperial (gpm, dash, ft/s).
4. Strict fluid & temperature limits – Valid only for low‑viscosity hydraulic oil (≤3.15 S.S.U. @38°C) at 18–68°C.
5. Preliminary reference only – Ignores pipe length, fittings, filters, and pressure drops; not for final design.
6. U.S. standard dash sizing – Uses SAE/JIC dash numbers (-32, -24, etc.) for direct matching with commercial hoses/fittings.
