about waterhammer in pipes?
916270
Water-hammer is the effect of non-compressibility of fluids and the physics of kinetic energy. It is avoided by providing damping in the system (most commonly an air cushion in the system) that will allow the kinetic energy of the fluid to be damped out and absorbed, rather than being transferred to the pipe system as an impulse (like a freight train hitting a barricade). The air cushion allows the fluid to decelerate gradually. Pipe friction in the cushion provides energy absorption, as well.

Vibrate, Fingers ,or if you have a detectable shower head use warm water

picture a water pipe that is 1/4 inch in size, and a water pipe that is 5 inches in size.\nWhich one can move more water?\n\nnow invision dial up and the small pipe and broadband as the large pipe.\n\nof course the use it to move more stuff.

Were the pipes replaced all the way into your house or basement? If so, there's a remote possibility that any components grounded to a plumbing pipe may now not be sufficiently grounded. \nIs the picture poor with an aux input (VCR, DVD,etc.)?\nI would look for other reasons first - coax, connections, input source and so on. It's unlikely the PVC is a concern.

Yes because of the water. The first and most important rule in plumbing is that eventually a gasket will leak. So you must be prepared. Maybe one in a million. You take the chance ?

It depends.  If the pipe is vertical and long enough you won't EVER push it all the way through.  Once the pipe is full enough, it will take 500 PSI at the base just to keep it in there!\n\nIt also depends on the length of the pipe (you could assume here whatever length of 1 inch pipe it takes to contain 50 cu inch of liquid, or 50/(PI*.5^2) = 200/pi inches) but more importantly on the viscousity of the liquid (water, which you can look up).  There is also frictional drag by the pipe, but I bet you are supposed to ignore that. \n\nFlow rate = pi*P*r^4/(8 * v*l)  where v is vicousity, P is the pressure difference between the ends of the pipe, l is the length of the pipe and r is the radius.  Putting in that length expression and dividing the volume by the flow rate to get the time, you end up with \n\ntime=pi^2*P*r^6/(8*v*vol^2)\n\nand vol=50 cu inches in this case\n\nThis makes the assumption that the length of pipe in question is s.t. it always contains 50 cu inches of water at any point in time,  and you just want to see how long it takes to push 50 cu inches out as you add more in the back end.  If you change the volume and pipe length as a function of time (the pipe is still the same starting length and starts full but no new water is added as the 50 cu inches moves down the pipe) you will have to solve a simple differential equation. Be sure to put down the appropriate expressions for how mass and volume of water are a function of length!

1. Contamination of the hydraulic fluid with water, very detrimental to the equipment.\n2. Dirt due to improper filtration.\n3. Worn metal particles due improper magnetic traps in the sump of hydraullic oil.\n4. Other liquids used on equipment due to leaky seals\nThe above can be found out by change of colour of hydraullic fluid, while changing filters, attending to seals and of course conducting mandatory checks of fluid over recommended intervals.  corrective and preventive actions will have to be taken based on checks.\nVR

well as far as i know word spout means to discharge or spew out

water has an anamalous behaviour. normally substances contract on cooling but water behavs in an opposite way meaning they expand on freezing\nat a very low temperature water freezes and expands.therefore the water pipes lines burst at very low temperatures. same with glass bottles containing water kept in a freezer explodes.\nhope that helps!!!

I'm sometimes scared of waterpipes, but only if I think about it too much.  But I am scared of those pipes that come off heaters that have all the insulation.  There's one in our attic that I have to step over every time I go up there, and it freaks me out.  The other thing I'm scared of are fire-sprinkers in my building, but thats just cause I'm afraid they'll go off and get my stuff wet.

Chlorine (Cl2) is dosed in water to disinfect gems & bacteria, so it might have an effect.Pressure pump does increase this corrosion due to the friction between the water & the pipe.

This is an Internet myth.  Lead in pipes (water pipes)_ is a hazard.  Lead in pipe organs is not.  The law you are worried about does not exist.

It shouldn't. You must have a problem with your plumbing.

An alarm valve is a check valve with a method of getting pressure or slight flow from an auxiliary port.  The alarm valve opens when pressure on the system side is low enough for supply pressure to open it.  then some water goes out the alarm port to a pressure switch or water motor gong.\n\nA deluge valve is a normally closed valve, opened by a stimulus from other than pressure on the system side.  Typically the stimulus comes from a heat detector for electrically operated systems, or loss of pressure in a pilot line.  The pilot line is provided with air or water pressure, and has fusible plugs or sprinklers for detection, mounted in appropriate locations.  If the pilot line loses pressure, the deluge valve opens automatically.  Manual operating features are always included.  Rarely, one finds deluge systems that are manually operated only.\n\n\nThe alarm trim can be identical for alarm and deluge valves.\n\nIf you are charged with designing a system in accordance with NFPA 13, a fire department (siamese) connection is required.  Exceptions are:\n\n1. Fire suppression forces (if any) do not have the facilities for providing water to the fire department connection.\n\n2.  The authority having jurisdiction waives the requirement.  Of course you would want the owner to agree also.

They probably pump it up and fill it. Lke allwater towers there are pipes going both up and down. Once filled though, they can leave it alone for awhile. Usually there are sensers inside that relay to a computer and alerts when the tower is getting low. In small towns I know sometimes they put too much water in and it isn't used. Thats why they sometimes flush it. But I would research the topic in an online enclycopedia.
