Are there any good design references or software available for calculating the air pressure balance in exhaust gas collection duct systems?

There are some commonly used software tools and resources that can be referenced: 1. The \"Code for Design of Building Smoke Exhaust\" provides formulas and methods for calculating duct air volume, which can be used as a reference. 2. The Autodesk Revit software includes a piping system analysis function that enables the calculation of wind pressure loss and air volume balance. 3. The Duct Calculator software from ESI (Environmental Systems, Inc.) can also perform similar calculations. 4. The HAP (Hourly Analysis Program) software is an air conditioning load and energy efficiency analysis tool developed by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) in the United States, and it includes a piping system analysis function. It is necessary to select appropriate methods and tools for design based on the specific circumstances of the project. .
