Duct Sizer is a calculator app that can use to calculate or evaluate duct sizes of HVAC Systems.

Duct Sizer comes with two main functions.
1. Calculate duct sizes based on the input provided by the user. As the output user can get a maximum of 5 ducts sized that match with the input parameters and flow velocity and pressure drop relevant to each duct size.
2. Evaluate duct sizes by entering duct size and flow velocity or flow rate. As the output user can get the pressure drop of the duct and flow velocity or flow rate.

To make the calculations easy, Duct Sizer is provided with several options including:
- Multiple unit support.
- Multiple duct materials.
- Multiple duct shapes.
- Save the most preferred values to repeat calculations with minimum inputs.

Currently, the maximum calculable duct height is limited to 10m and the flow rate is limited to 10,000l/s to improve the responsiveness of the app.
