Nozzle Air Entrainment - The Cause and Effect

We have recently produced a video series discussing Nozzle Air Entrainment for firefighters. In this series we took a look at 3 pairs of tests for a total of 6 videos. In this video we take an in depth look at nozzle air entrainment and hope this overall instructional video sheds a little light on the topic. Remember, you can reference the other test videos by viewing them in the overall Nozzle Air Entrainment Playlist. We will provide that playlist at the bottom of this article, but you will also be able to find the playlist on our website by clicking here or on our YouTube channel.

Nozzle Air Entrainment Round 2 - Video Series

This is the second round of videos from our Nozzle Air Entrainment Video Series. In these two videos we will look at the interior attack of a vent limited situation. This will give you a good idea of how a nozzle can over pressurize a space regardless of fire or heat. This is simply air entrainment causing this over pressurization. We will use two videos, one for the smoothbore and one for the fog nozzle. This will pick up where we left off with Tests 1 & 2. If you haven't seen the first two tests click here to watch those videos.

Thank you for watching and keep an eye out for the next round of videos. We still have two more experiments to go and will release those next week.
