  Airflow in Ducts. Learn what happens in the duct. Understand static pressure, velocity pressure, total pressure, dynamic losses, and friction losses—in practical terms that you can use. This book will show you how duct fittings affect airflow. Read this book and you will easily understand all you need to know about airflow.4/5(6). Airflow in Ducts was a very valuable book for our students here at J&J Air Conditioning. I found the book very concise and clear to technician-level students and was a great help to teaching the subject. Get Textbooks on Google Play. Rent and save from the world's largest eBookstore.

Learn what happens in the duct. Understand static pressure, velocity pressure, total pressure, dynamic loss, and friction losses—in practical terms that you can use on the job. Learn how duct fittings affect airflow. This book gives you another step to HVAC success. You will gain an understanding of airflow that few in the industry have. Airflow in Ducts is a fairly basic book starting with low level science and physical properties for air itself. There are useful sections, however, dealing with actual hvac duct sizing methodology. Addittional information will be needed from other resources, for example covering individual component pressure drops, to be able to size an actual system of ducts/5(9).   Friction is a resistance which slows down airflow. The flow of air creates friction as it rubs against the side of the duct, and the friction creates resistance to the airflow. Think of blowing through a piece of garden hose 6 inches long. You . The total energy per unit volume of air flowing in a duct system is equal to the sum of the static energy, kinetic energy and potential energy. When applied to airflow in ducts, the flow work or static energy is represented by the static pressure of the air, and the velocity pressure of the air represents the kinetic energy.

The airflow to each room should be proportional to each room’s load. In other words, if one room accounts for 10 percent of the total load, then it should get 10 percent of the airflow. Sorry for the shameless plug, but my book covers this pretty well.
