4. The indoor fire hydrant is a fixed indoor fire-fighting equipment in factories, public buildings, warehouse,etc.

Indoor fire hydrant is the connecter in the water piping network, including one valve with single outlet, One Valve with double outlet and double valve with double outlet etc. It's used to offer assistance to control the fire.

Rated working pressure:16 Bar

Strength test pressure:24Bar

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: Has the hydrant been discharged from the main engine?: The main fire engine hits the automatic state, and the fire control cabinet hits the automatic state.

Q: Fire hydrant, disk hose, service life: Any kind of pipe work is carried out in the load and displacement under the condition of certain, keep constant load and displacement or rarely change, known as static working condition; when the load and displacement of continuous cycle alternating changes. In a circle in a dynamic state. Because of the two working conditions, the mode of damage or failure is different.

Q: i am going back to work as a glazier but its been about a year and a half since ive been gone and i asked for the company's list of handtools required but the guy forgot to bring it with him. we do big commercial projects. mostly curtain walls. im pretty sure i have all of my tools from the last time i know i have my specifics (i.e. suction cup, vynil roller, bulk caulk gun, saftey harness, screw gun) i just need a list of hand tools. thanks: Hmm..it wouldn't be thundering INSIDE, now would it? What is it in that sentence? A better sentence would be: Outside, there was thunder and lightning. To modify your original sentence to make sense, you would need to say: It was thundering and lightning was flashing. (You wouldn't need outside. It's understood that such occurrances do not happen indoors.) Lightning only acts as a noun, not a verb. If you only put this up to be cute, I must say that its silliness does raise a chuckle. hee.

Q: I'm making a CD for somebody for the holidays And I wanted to rubber cement a piece of paper to the front of the CD (with the tracklist, album art, etc.). I wasn't sure if the rubber cement would damage the CD, though. Does anybody know if it will?: No, its just an infraction. You're insurance will only increase if you get a moving violation or if you are involved in an accident

Q: A 200-foot-long fire hose with an inside diameter of 2.5 inches delivers 250 gallons perminute of 70°F water. The average velocity of the water in the hose (for this flow rate) isapproximately 16.3 ft/s.a) Is the flow of water inside the hose laminar or turbulent?b) What is the frictional pressure drop along the 200 ft length?for (a) i got Reynold's number, Re 322745 thus it's turbulence (correct me if i'm wrong.however, I can't do (b) part, please help: they all have a capital letter in them idk

Q: I find them very annoying and recently broke eggs while trying to push my cart over them. You can't go around them and it doesn't matter how slow you go. This is a fairly new super center so I thought maybe this is something new. I looked online and couldn't find anything.: His argument is that the place of work of the vice chairman is a separate place of work from the President. in fact, it is. The vice chairman is the President of the Senate, and answerable for breaking all ties interior the Senate. greater beneficial, it is achieveable that a President ought to and can have a vice chairman from an opposition occasion. Say working example that Bloomberg enters the race with McCain or Lieberman as a vice chairman. Say he splits the college to evade a plurality from choosing a President choose. Then the vote is going to the residing house, and so on. you're starting to be a vice chairman who's a republican to a Pres who's a Dem. needless to say, the president can't hearth the vice chairman, nor can the president stress a vice chairman to provide up. that is a factor of nuance. in my opinion, I agree that it is a few thing that needs to be defined. Is the place of work of the vice chairman a legislative place of work, and government place of work, or a hybrid of the two? it is as of yet completely defined, and merits extrapolation. could be some thrilling factors to examine.

Q: I just bought a doberman female puppy.Just i want to know how to bring up that the procedures.thank you: those plastic radiators would be warmth welded yet this has a tendency to be non everlasting at ultimate. The radiator frames would be pulled back into shape through stripping the areas away to offer get right of entry to and installation a chain or resembling the bent area and pull it back into shape. Ive seen this achieved utilising yet another vehicle or chain/cable pulley. Its not ordinary and you need to do extra injury in case you don't be conscious of what you're doing. i desire to propose having it achieved professionally or get some help from somebody that is familiar with what to do.

Q: it's not all that costly or time consuming as compared to ceramics (especially since you don't need a kiln), it's less messy and far more durable than plaster, and it seems like once you got it the hang of it, resin casting would be a pretty awesome hobby. am i missing something here? if you do resin casting, what books, sites, and/or supply companies do you recommend? thanks. :): Flour, baby powder, talc powder,starch powder. Non conductive things.

Q: my alarm clock (Jimi Rocker Clock by brookstone) runs out of battery every single morning. i put new batteries in last night and by the next morning they were burned out. anyone have this problem or solved it?thanks!Sara: LOL FUNNY!!!
