This app works as a Ductulator and Pressure Loss (friction) calculator which has the following functions.
- Converts Duct Shape or Size to Another
- Determines Sizes for a Given Friction Rate
- Determines Sizes for a Given Velocity
- Determines Sizes for a Given Velocity and a Friction Loss Rate (simultaneous output)
- Determines the Airflow Rate for a Given Size and Friction Loss Rate
- Calculates Friction Loss
