Q: There is a 1/2 copper pipe coming up from under the foundation of my house that just sticks out of the ground about 12 or so, and what I believe is 1 1/4 PVC pipe coming from the water heater (maybe a drain?) and doing down the same hole. The hole is plugged up with firestop, but I‘m trying to make the closet the water heater is in a little easier on the eyes, new paint, etc. Is this copper pipe still in some kind of service? or could I cut it off and fill it, too, with firestop before painting the closet floor (bare concrete) with some kind of concrete/garage paint?: The advice of William B above is good. You usually should have a professional help with plumbing problems. The copper pipes may have a union, If so it becomes much easier to fix. A union looks like one big nut (2 or so)with two smaller nuts on either side (1 or so) If not it will take a torch, solder and some new fittings. If you decide to fix it yourself,turn off the water at the valves above the water heater. If their is a union, use two wrenches to loosen the nuts. Once undone, you should be able to undo the pipe going into the water heater. check it for any problems, rust corrosion, etc. If it is just loose, get some teflon tape and wrap it on the treads and retighten the pipe. Then connect the union back up. Make sure you use two wrenches and tighten pretty well. It is best to have help of someone who has installed a water heater or done plumbing work to help.

Q: A sheet of copper is placed between the poles of an electromagnet with the magnetic field perpendicular to the sheet's surface. When the sheet is pulled out, a considerable force is required, and the necessary force is larger with increased speed. Explain why.: As soon as the copper conductor moves through the field the changing flux linked to it creates an induced emf within it. This emf (called a back emf) is generated in opposition to the flux change causing it .. in accordance with Lenz's law. The 'opposition' is due to the back emf driving an induced current that creates an electromagnetic field in opposition to the existing field .. the repelling forces create the opposition to the conductor's movement. Induced currents occurring like this, within relatively large areas of a conductor, are known as 'eddy currents' as they tend to flow in circular paths. Because copper is a good conductor, there is hardly any resistance to an induced current flow .. even a small emf can create a large induced current .. so creating a large opposing force. Moving the conductor faster increases the rate of flux change linking with the copper .. so the back emf is higher, giving a greater induced current and opposing force.

Q: How do I polish my copper box? It has gone a brown colour and it looks very old but its quite new. The copper is also rusting how do I get this of?: If it is rusting then it is not copper. (rust is an iron thing) As has been mentioned get some metal polish and clean off the tarnish. Then apply a thin coat of lacquer to keep it a shiny copper color..

Q: My house is approx. 50 yrs old. All of the water lines inside the house are copper. I would guess these copper lines are original to the house. However, when you get to say a toilet or a sink, it turns into a galvanized piece. I'm guessing the copper runs right up to the wall, then they used a galvanized piece through the wall. Why would they do this? I replaced some shutoffs recently and noticed the galvanized was quite corroded inside. Most of the house has very strong water pressure, but a couple of the bathroom sinks are quite a bit weaker.: To restore pressure to the fixtures. Change the nipples to brass with new angle stop valves this should restore the pressure at those fixtures you mentioned. Don't forget to shut off the water at the house shut off valve.

Q: My bag of horse treats says &quot;Do Not Feed to Sheep or other Copper Sensitive Species.&quot; Can I feed them to my pigs? I couldn't figure if they are copper-sensitive or not. Thanks!: Pigs don't usually fall into the category of copper sensitive animals, but it would be a good idea to avoid it. If a treat is labeled for horses, it should only be given to horses. The best solution I've found is cheap vanilla wafers. Not the brand name ones in the box, the ones in the plastic bag. They have almost no calories and animals love them. We give them to our dogs, horses, mules, hogs, pot bellied pigs, sheep and goats. You don't have to worry about copper or sulfur or anything like that.

Q: I'm doing a chem lab and I have to state which is more reactive. We put a piece of copper wire into a beaker full of silver nitrate.So which is more reactive?Copper (Cu) and silver (Ag) are both transition metals and nitrogen (N) is a halogen. Would being a halogen make nitrogen more reactive?AHH! Please help! I'll choose a best answer! :)Thanks in advance.: Copper Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag The copper reacts with the nitrate polyatomic ion to create a solid. And, nitrogen is not a halogen. It is is group 5A, while halogens are group 7A. Your idea that halogens are much more reactive is correct, but nitrogen is not among that category. Does that help you understand why? If not, ask some more.

Q: The pipes in my place are made of either PVC and Copper, now the temp outside is close to 22f, and obviously one of my PVC pipe is frozen. I am worry about the pipe may go bursted.I believe I once heard someone said that PVC pipe is in fact stronger than copper one and the chances for PVC pipe to burst is relatively low. I wonder if it‘s true that PVC pipe is less vulnerable?: Often PVC piping is used for drainage and copper for supply lines. If you had PVC and copper pipes with the same inner diameter, correctly fitted joints and water inside at the same pressure levels, the PVC will burst first as the water freezes. In a drainage situation, there is a lot of air in the pipes -- and thus provides room for water to expand (as it freezes). So, there is a lot less threat of a PVC bursting. If given the choice of piping, nowadays. go with the new PEX piping. Cheaper than copper and has a greater strength than either PVC or copper due to the fact that it (PEX) can expand and contract. If you find yourself in a situation where you are concerned that pipes will freeze, the best thing to do to quickly rememdy the situation (until you can restore heat) is to turn on of your faucets on to a trickle. As long as the water is moving, you'll be okay. Good luck.

Q: Should I replace my main water line pipe with plastic (black well pipe) or with a copper?: When you find out the price of the copper it might make up your mind for you. The guy who did my new well used a type of plastic pipe that is blue, very heavy duty.

Q: Where would I find tables for K values of different diameters and different bends in pipes?: Sorry but ,you can't just say k without saying what does it mean,Does it mean stiffness of the pipe or what ?

Q: If the air conditioner is re assembled, will it damage the copper tube?: Air conditioning pipe to minimize the number of disassembly and disassembly often has some damage, (brass of the demolition more hard, easily broken, sharp anti disk attention circle).
