Duct Fitting Loss Coefficients: elbow_90_mitered_double_vane
Loss coefficients (C-values) for duct fittings — elbows, tees, transitions, entries and exits per ASHRAE Fundamentals and SMACNA. dP = C * Vp where Vp is velocity pressure.
| fitting type | size or range | C0 (dimensionless) | description | geometry notes |
|---|---|---|---|---|
| elbow_90_mitered_double_vane | all | 0.24 | 90-degree mitered elbow with double-thickness turning vanes | Double-thickness aerodynamic vanes; typical commercial installation |
