What is the term for pressure lost due to turbulence in air flow?

• A. Static loss
• B. Dynamic loss
• C. Friction loss
• D. System loss

Answer: (B)

The term for pressure lost due to turbulence in air flow is dynamic loss. This occurs when irregular air movements increase the resistance within duct systems, leading to a drop in pressure. Dynamic loss is particularly significant in systems with bends, elbows, or transitions, where changes in airflow direction can create turbulence. Understanding dynamic loss is essential in the design and analysis of HVAC systems, as it helps professionals ensure that systems can effectively move air throughout a building while maintaining efficiency. By accounting for dynamic losses, engineers can size ducts appropriately and design layouts that minimize turbulence, aiding in optimizing airflow and energy consumption.
