What should be done to ensure ducts do not obstruct exhaust flow?

To ensure ducts do not obstruct exhaust flow, avoiding sharp bends and obstructions is essential. Duct systems are designed to facilitate the efficient movement of air or exhaust, and any disruption in the airflow can lead to decreased efficiency, increased energy consumption, and potential safety hazards. Sharp bends can cause turbulence, increasing friction and resistance against the flow, which may lead to inadequate exhaust removal. Obstructions, whether from debris or improperly sized ducting, can further hinder the airflow. By maintaining a smooth and unobstructed path for exhaust gases, you can optimize the performance of the ventilation or exhaust system, ensuring that it operates effectively and safely.

While using flexible materials or sealing joints can contribute to the overall efficiency of the duct system, the primary concern for unobstructed flow lies in the design and layout of the ducts themselves, specifically in avoiding sharp angles and other physical impediments.
