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.
