 s


A hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water, on the order of 350 kPa (50 lbf/in²) (this pressure varies according to region and depends on various factors including the size and location of the attached water main). This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams. The hose may be connected with a threaded connection, instantaneous "quick" connector or a Storz connector. Care should be taken not to open or close a fire hydrant too quickly, as this can create a water hammer which can damage nearby pipes and equipment. The water inside a charged hoseline causes it to be very heavy and high water pressure causes it to be stiff and unable to make a tight turn while pressurized.  


Q: any flight attendants or airhostes over here plzz help me with this question
The higher the number, the more serious the fire. Alarms notify the stations to send out more trucks, firefighters and equipment.
Q: Do candles set off smoke detectors?I live in a dorm room and I was wondering if it would be undetected if I lit a candle :)
A black hole is an object in spacetime that's gravitational field is so strong that light cannot even escape. The only danger is if you passed through the event horizon (the point of no return)
Q: if not your OWN kid or relative
I would take it back. Everything should work on it. Should be designed not to pick up static. Maybe keep your cell phone away from it cause the signal can cause electrical interference
Q: And the reasons of that system being the best and most common?
Demosthenes wrote : grow a mustache, put on a studded collar, and have people call you Larry from now on. I agree, and would just suggest that you get down to your nearest local Hog trough, get your face into the chow, and put on an extra 200 lbs of pork, and that should put you right in with the 'out' crowd. On a serious note, make one of your items on your 'to do' list be to ride the Blue Ridge Parkway, all the way from Virginia to Georgia, gotta be one of the best biking roads in the world. Have fun. :-)))

The other man connects the hose and the valve door.4, turn the valve counterclockwise, water can be ejected. Note: electric fire should be determined to cut off the power supply.
Q: Would a tennis ball on the end of an umbrella reduce its lighting rod effect?
A large force of highly trained archers can be a daunting opponent to face. Some historical peoples such as the Spartans of the Greco-Persian wars saw the bow and arrow as the weapon of a coward as it killed from a distance, but nonetheless it was still a formidable weapon. Even the highly trained and disciplined forces of the Roman Legion weren't invulnerable to all archer fire. The Composite bows used by Parthia for example could penetrate the Roman scutum shield and still have the driving force to pierce a legionary's lorica armor and proved the decisive factor of Marcus Crassus' invasion of Parthia. So yes, well-trained and well equipped archer units can prove a formidable weapon in battle. But they are highly vulnerable to cavalry attacks. Next time you find yourself going against archers be sure to bring some light cavalry with you.
Q: I usually paint with the cheaper stuff, but I came across some real nice Grumbacher Pre-tested oil paint and bought it. It was the first time I bought paint with health labels. Most contain lead, and the ones that don't still say that California thinks it may cause cancer / do not spray apply.My question is, how safe do I need to be? Should I wear gloves and avoid all contact? Does my area need to be ventilated? Or should I just refrain from using the paint as a condiment?
Really old, huh? Ok how about: Gunpowder The wheel Knives Axes Bows Arrows Baskets Pottery Guns The fireplace Utensils for cooking and eating with Canteens Maps Compasses Telescopes Sun dials Surveyors tools Ox/donkey carts The wheelbarrow Shovels Paper Ink Pens Mirrors Candles Oil lamps Bells Musical instruments As for what a lightning rod, it was an invention by Ben Franklin to prevent lightning striking a house and catching it on fire. You might still see it on some houses. People would put one or more lightning rods up on the roof of their houses so as to prevent lightning damage. A lightning rod is this metal rod that sits up on the roof with a wire running from the roof down to the ground. Thusly rather than strike the Roof the lightning would strike the lightning rod and then run down to the ground. You're going back to the mid to late 1700s for that particular invention.
Q: My XT500 feels like there is a bump in the road every 20m at higher speeds. What could it be?
