Calculation method
Calculation method
Friction pressure loss (Pa)
Darcy-Weisbach dp=f(L/D)rho V²/2; head=dp/(rho g).
Friction head loss (m)
Darcy-Weisbach dp=f(L/D)rho V²/2; head=dp/(rho g).

Assumptions & limits
Assumptions & limits
- Darcy friction factor, not Fanning factor; straight pipe only. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Darcy friction factor, not Fanning factor; straight pipe only.
