Where firefighters come to talk training

Geometry, Physics and Chemistry

I really asked me when I was in high school, why the heck I would serve these materials in my life of adult. Who knew that today not only use these materials but many more, such as: math, calculus, and others to help firefighters battle the monster that the fire is.

There are some methods today to fight the fire, one of them is indirectly, That means applying in hot environment or atmosphere water to create large amount of vapor and controlling fire and displacing oxygen. To understand more about this, we must understand that water boils at 272°F being 1,700 times more volume than liquid state, it is also important to know, recognize and calculate three kinds of volumes in this situation, volume of the room, the volume of water vapor and water volume to create steam.

You see that knowing and understanding the basic aspect, we effectively discharged one second of water from our hose section at 30 GPM 60 degree-cone fog stream, just because you have discharged in that brief second has generated an out of approximately of 1.6 liters of water.

To understand more of this explanation must take in mind that hot air unit to 1,000°F weighs 0.45 Kg and occupies 1m³, this single unit is able to vaporize 100 grams of water or what is equal to 100 milliliters so that they occupy 0.37 m³ in vapor form.

If we apply this one second discharge stream of water with a cone fog under that temperature 1.6 liters would be applied what that equivalents to 5.92 m³ steam (single calculation).

Being that if we have a room approximately 50 m³ would have to apply about 10 times more water to create enough steam to saturate the room, cool and displace oxygen, but remember that we do not work with 30 GPM but between 250-350 GPM in our hoses which indicates that second of water at 60 degree-cone fog stream is very likely that the atmosphere has cooled considerably.

Remember to share what you know with your brothers and talk about it, do not know if you can call instructor or mentor but what I do know is:

If you learned something from me and save a life is worth it!!

Geometría, Física y Química

Yo realmente me pregunté cuando estaba en el colegio, para qué carajo me servirían esas materias cuando sea adulto. Quien diría que hoy en día no solo uso esas materias sino muchas más, como: matemáticas, cálculo; y, otras para ayudar a bomberos a combatir ese monstruo que es el fuego.

Hay algunos métodos hoy en día para combatir el fuego, uno de ellos es de manera indirecta es decir aplicando agua en ambientes calientes para crear gran cantidad de vapor en la atmosfera desplazando el oxígeno y controlando el fuego. Para entender un poco más esto, debemos entender que el agua hierve creando vapor a los 100° C siendo 1.700 veces más en volumen que en estado líquido, también es importante saber, reconocer y calcular tres clases de volúmenes en esta situaciones, volumen de la habitación, volumen del vapor de agua y volumen del agua para poder crear el vapor.

Ya sabiendo y entendiendo eso veamos el aspecto básico de descargar efectivamente un segundo de agua de nuestro tramo de manguera cargado a 30 GPM, usando un cono de poder de aproximadamente 60°, el simple hecho que haya esa descarga en ese breve segundo ha generado una salida aproximada de 1,6 litros de agua.

Para poder entender algo más de esta explicación hay que tomar en cuenta que una unidad de aire caliente a 538°C pesa 0.45 Kg y ocupa 1 m³, esta única unidad es capaz de vaporizar 100 gramos de agua o lo que es igual a 100 mililitros haciendo que esta ocupe 0.37 m³ en forma de vapor.

Si aplicásemos ese segundo de agua con un chorro “cono de poder” bajo esa temperatura en un cuarto estaríamos aplicando 1.6 litros lo que nos equivale a 5.92 m³ de vapor (regla de 3 simple).

Siendo, que si tenemos un cuarto de 50 m³ aproximadamente tendríamos que aplicar cerca de 10 veces más agua para crear suficiente vapor para saturar esa habitación, enfriar y desplazar el oxígeno, pero recordemos que nosotros no trabajamos con 30GPM sino entre 250 a 350 GPM en nuestras mangueras lo cual nos indica que un segundo de agua a 60° en cono de poder es muy probable que haya enfriado notablemente el ambiente.

Recuerden compartir lo que saben con sus hermanos y hablar al respecto, no sé si me pueden llamar instructor o mentor pero lo que sí sé es:

Si aprendieron algo de mí y salva una vida habrá valido la pena!!
