Ductwork sizing, calculation and design for efficiency - HVAC Basics + full worked example

This video tutorial covers the design and optimization of ductwork systems for mechanical ventilation. It explains how to design a basic ventilation system using the equal friction method, calculate mass and volume flow rates, and optimize ductwork efficiency. The tutorial also discusses the importance of duct shape, material, and fittings in reducing dynamic losses. Finally, it provides a step-by-step guide to sizing ductwork and calculating pressure losses, using a small engineering office as an example.
