Why use 1.57? There is no device on any pumping vehicle that can be read to a hundredth. 1.5 would be totally adequate.

thank you good video

We doing online training so I'ma send this to our training sessions

Thank You!

Thanks

GREAT Video! It has helped my studies for AO Promotion. Thank You

In order to "overdrive your siren" you would have to be travelling with a combined speed (meaning that the person's speed driving away from you would have to be added) of more than 767.269 MPH. Give or take based on humidity and other factors. But yeah. The speed of sound is much greater than that of a fire engine. People may not hear your siren because of a whole myriad of reasons, but "overdriving" it probably is not one of them.

Super job explaining! Made very simple. Thank you

Great video. This helps me a lot

29.7 o 29.84 ???

keep in mind, they now require all personal to have helmets off inside a apparatus.

What is an EVOC. Is it an online class or an offline class? How long is EVOC training? Do I need a driving license to learn this course? Will we have to drive a vehicle in this course?

Very well explained & Super Amazing nd informative video. Thank you

Thank you for the help! Learning this in the academy right now

Great video.

Why is nozzle pressure no longer square rooted?

Why do US fire departments use tankers so much, would not a HVP save considerably in manpower requirements?

Thanks for the lesson, some learning and safety tips grabbed.

So the number (29.7) where does that number or constant come from?

HOW TO CALCULATE THE REACTION FORCE IN FOG NOZZLES?

Awesome videos. BIG HELP cause I was lost. Thank you sir.

Before you start...whens the baby due hehehehehe

How we get 9.48

The first department I has on we would set up a fill site with enough lines to fill up to 3 tankers at one time. A typical 1500 gpm pump may flow 2200 gpm from draft. Being from the Mabas Division 101. Back when we had a cork factory on fire we flowed sustained 6000 gpm. At times we were flowing 8000 gpm, the hard thing was refueling the Engines at the fill sites. Fill sites seem to always have tankers 2 and 3 deep refilling having one almost full one about 1/2 full and one backing in to fill. On a five alarm plus two interdivionals. We had equipment north to south from Milwaukee to Chicago. This took 4 fill sites one artesian well flowing 1000gpm 4 Fill sites on a lake each with a Engine Qmax Hale 1500 GPM pumps. And 2 Firefighters and a Engineer. As you are filling one at maximum gpm let the extra pump gpm fill a second tanker backing in a 3rd and connecting it up. Keeping one at the empty tanker and one at the nearly full. As the nearly full finishes filling. That firefighter shuts off the filling lines and then opens fully the 1/2 full tanker and half opens the valve to the empty tanker. Then both firefighters can release the full tankers lines and pull them back 10 to 15 feet. And then the process starts all over again. Of course all our tankers had a 3 inch and a 4 inch intake. Most had 3 way 10" dumps on the rear and were 3500 gallons. Also all our portable tanks were interconnected with the drain sleeves using Fol-da- Tanks drain sleeve connectors. Water supply needs its own channel, fill locations use a 5way manifold with only 2 2.5 gated outlets and 3 5" gated outlets. 50 ft 5" sections make this easier. Also having a rehab mobile pickup or van to bring support supplies such as Gatorade and food to fill sites helps keep things moving quickly. When running multiple fill sites it is needed to assign tankers to fill sites. These fill sites need to be fairly large and can be set up alongside a roadway, large boat launch, but not a dead end street only forcing tankers to back up short distance is the second best a truck length or 2. A straight pull up and drive out is best. Using a road way always keep one lane open. Marking the stopping points with reflective traffic cones. We couldn't have asked for a better time to have a ISO certification done that day.

where can I find the constant demonstration, which is used in this formula, 29.7 ???

What's the time limit?

In order to place the Front Mount Pump in Pump Gear, there was a lever directly under the Intake of the Pump, with a Small Knob on the lever. Pull the Knob out toward you, and turn the Pump Gear Handle to the Opposite Side from it's original position, and release the Knob, this placed the Front Mount Pump into Pump Gear, with the Ability to Pump, and Roll.

I remember an old 1956 Ford Brush Truck with a Front Mount Pump, and to place the front Mount Pump in Pump Gear, t

thank you for this. its a big help

what does the 1.57 represent and if you are trying to figure this out for handlines, does the size hose matter?

nice things
