SMACNA Duct-U-Lator 4+

The SMACNA Duct-U-Lator is a digital version of the classic duct sizing tool. It is used by HVAC professionals to quickly size rectangular, round, and oval ducts for optimal air flow in ventilation systems. The app simplifies the calculation process, helping users determine duct dimensions based on variables like air volume (CFM), friction loss, and air velocity.

Key features include:

- **User-friendly Interface**: The app offers a simple, intuitive design that mimics the physical ductulator, allowing for quick inputs and results.
- **Multiple Duct Types**: Supports rectangular, round, and oval duct sizing, giving flexibility in various design scenarios.
- **Real-time Calculations**: As users adjust inputs, the app instantly updates results, speeding up the design process.
- **Enhanced Accuracy**: By automating complex calculations, the app reduces human error and ensures more accurate results compared to manual methods.

This app works as a Duct-U-Lator 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

The SMACNA iOS Duct-U-Lator is a valuable tool for HVAC engineers, contractors, and technicians looking for a portable and efficient way to perform duct sizing on-site. It combines the convenience of modern technology with SMACNA's trusted guidelines for air distribution system design.
