Hey there guys, Paul here from TheEngineeringMindset.com. In this video, were going to be looking at ductwork systems for mechanical ventilation. Were going to look at how to design a basic ventilation system with a full worked example. Well also look at how to calculate the losses through the bends, the tees, the ducts and the branches, well consider the shapes in the material that the ducts are made from to improve the efficiency, and then lastly, were going to look at how to improve the efficiency and optimize the design, using a freemium software for fluid flow simulation by SimScale. Methods of ductwork design, there are many different methods used to design ventilation systems, the most common ways being velocity reduction, equal friction and static regain. Were going to focus on the equal friction method in this example, as its the most common method used for commercial HVAC systems, and its fairly simple to follow. So well jump straight into designing a system. We use
