Which specific (e.g., elbows, tees, or transitions) do you need to analyze right now?
$$ \Delta P = C \times P_v $$
The software inputs airflow velocity, air density, and fitting dimensions to calculate total pressure loss. If you cannot see the 'Loss Coefficients (pdf)'
Data can be viewed and printed, making it easy to create reports and project documentation.
The database isn't just theoretical; it has real-world uses:
