  • The exact input values tested and units used (PSI / Bar, GPM / L/min)
  • The observed output vs. your expected calculation result
  • The governing engineering standard or formula citation (e.g., Hazen-Williams, NFPA 291, Crane TP-410, ISO 5167)

Response timeframe & policy

Our editorial team reviews all technical inquiries within 1 to 2 business days.

Resolved formula discrepancies are published to our Calculation Errata Log in accordance with our Editorial Policy.
