How it works
Calculate internal pipe velocity from volumetric flow and inside diameter.
Formula:
Q = flow / 1000; A = πD²/4; v = Q / A.
Before you use the result: Preliminary calculation only. Verify final MEP/electrical sizing and safety requirements with the applicable standards and qualified professionals.
Practical use
Use design flow, electrical and equipment data from the latest project information. Final sizing must consider the applicable code, pressure losses, temperatures, power factor, manufacturer limits and system interactions.
- Keep units consistent with the source information.
- Use project-specific densities, pack sizes and coverage rates where provided.
- Round purchasing quantities to supplier packaging and delivery rules.
