Welcome to r/EasyDuct ๐
Hi everyone,
I'm Iman, a mechanical/HVAC design engineer and the developer of Easy Duct Calculator.
Easy Duct helps you:
- Size ducts from airflow + velocity or friction rate
- Check velocity and friction loss for a given duct size
- Work in both IP and SI units
It's free, with no sign-up, and available on Android, iOS and Windows.
Use this community to:
- Ask questions about the app or duct sizing
- Report bugs (please use the Bug Report flair)
- Suggest features you'd like to see
Pipe and Steam calculators are also in the works, so stay tuned!
Thanks for checking it out.
