Firefighter putting out a fire using Bernoulli's principle

TDIL: "Firefighters can utilize Bernoulli's principle to help extinguish fires by creating a low pressure area that draws air and smoke out of the structure. Here's how it works: When water is sprayed from a fire hose nozzle at high velocity, it creates an area of low pressure around the nozzle stream due to Bernoulli's principle. This low pressure area causes air inside the structure to get pulled towards the nozzle stream and out through openings like windows. By directing this high-velocity nozzle stream out of a window or opening, firefighters can effectively ventilate the structure and remove heated gases, smoke, and air that feeds the fire. Depriving the fire of oxygen starves it and helps extinguish the flames more quickly. So in essence, Bernoulli's principle allows firefighters to use their hose streams not just to apply water, but also to create a controlled ventilation path that removes combustible gases and heat, making interior fire attack safer and more effective. This tactic demonstrates the practical application of Bernoulli's principle in firefighting operations.

Bernoulli's principle, named after the Swiss mathematician Daniel Bernoulli, is a key concept in fluid dynamics that relates pressure, speed, and height. The principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or the fluid's potential energy. This principle is based on the conservation of energy and can be applied to both liquids and gases. It's a fundamental concept in various engineering applications, including aerodynamics, where it helps explain the lift generated by an airplane wing. In essence, Bernoulli's principle says that when a fluid flows faster, it has a lower pressure, and when it flows slower, it has a higher pressure. This principle is the reason why airplane wings are shaped the way they are - the upper surface is curved, causing the air to flow faster over the top, creating a low-pressure region, while the air flows slower under the wing, creating a high-pressure region. The difference in pressure creates an upward force, or lift, on the wing. It's also the reason why a shower curtain can be sucked inwards when you have a running shower. The water flowing from the shower head creates a high-speed, low-pressure zone. The air outside the shower is at normal atmospheric pressure, so the pressure difference causes the curtain to move inward. So, the next time you're on a plane or in a shower, you can thank Daniel Bernoulli for helping to explain some of the physics at work!

Science will save ur life. Respect nerds.

And now... with a cola :

The window being open is fueling the fire with oxygen and a backdraft. Spraying the water this way reverses air pressure and chokes the fire of is oxygen fuel source.

Who'd have thought you could fight a fire by squinting water away from it?
