- Q: What are the differences between the copper and aluminum tubes used in the installation of air conditioners?
- In recent years, the air conditioning connecting pipe, in addition to copper pipe, more and more used to replace a large number of aluminum tubes, then what exactly is the difference between copper tube and aluminum pipe? What are the advantages and disadvantages of using copper tubes and aluminum tubes? The first said copper, copper is high cost, good ductility, resistance to oxidation, bellbottom do good pressure resistance, not easy leakage of refrigerant, disadvantage is high cost, long time use will harden aging, when some air conditioning after repeated use of copper copper disassemble easily broken is the truth, when moving a lot replace the copper tube, so as to avoid air conditioning problems.
- Q: the reaction between Cu and HNO3 is clearly unusual. But is my explanation and understanding for why they react correct"the HNO3 is an oxidizing agent thus turning Cu to Cu2O. In the form of copper oxide, the reaction between Cu and HNO3 will happen?"--if it is wrong may someone please explain why the reaction occurs
- Hi John: The reduction potential for Cu (+0.34 V) is above that for H2 (0.00 V) and so copper will NEVER displace H2 from dil HNO3 (I've seen several times on this forum views to the contrary). Conc acids however have a whole different chemistry to dil strong acids. In very conc HNO3 (i.e., 100%) Cu is passive for reasons not understood but may be due to a protective CuO coating being formed. In conc HNO3 it is a strong oxidizing acid. I knew the rxns of Cu with somewhat less conc HNO3, but after looking in my texts the conc was only given for the NO production (C&W) [1]. Then I recalled seeing a video of Cu and conc nitric and here it is [2] with equations: Cu(s) + 4HNO3(aq) ——> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) They are obviously using commercial conc HNO3 (~70%, ~16M). In the next exp they say dilute HNO3 but that isn't true (C&W says 8M HNO3) which I recall is about right. 3Cu(s) + 8HNO3(aq) ——> 3Cu(NO3)2(aq) + 2NO(g) + 4H2O(l) Well there's another one solved! Cheers, drp
- Q: copper pipe type L: 20feet long and 2 inches wide.how much does it weigh???
- If it's 2 O.D. the I.D. must also be known in order to get the thickness of the copper. Without it the calculation can't be performed. (Having looked it up, Type 'L' 2 copper pipe is . 2.125 O.D. x 1.985 I.D. Volume of O.D. 1.0625 x 1.0625 x 3.14 x 240 851 in?. Volume of I.D. 0.9925 x 0.9925 x 3.14 x 240 742 in?. 851 - 742 109 in? of copper. Cu. density 9.0 g/cc about 144g/in?. 109 in? x 144 15.7kg mass of copper. (35 pounds).
- Q: I found a hairline crack on a copper pipe that‘s buried underneath our garden that runs into our main house. Water has been leaking from the hairline crack. Is there a way to patch the hairline crack without having to replace the pipe?
- If you want a quick fix that will last use marine silicone, get it at boat stores it works like a charm. Its a pretty good price too it is meant to withstand water pressure. If they dont have marine silicone at the boat store take a plastic tube slice one side and fit it around the copper piping with the crack, next melt it slowly onto the pipe this should work. If your into more expensive stuff weld it, but make sure the temperature isnt too high just enough or it will melt the copper pipe and also make sure your using a metal that melts at lower heats definetaly not iron. Happy fixing! If you have any more questions email me!
- Q: home is 4 years old and i was told that all the pipes need to be replaced because we have been having constant pipes leaking with pinholes and had to replace sheetrock and now hardwood floors damaged from the leak and it is ongoing builder just sends contractors to give me estimate but isnt taking responsibility for the inferior pipes or construction this home was sold to me for over $400,000 and is becoming a money pit
- If its cabin filters your speaking approximately they are placed on passanger area under the sprint above the floorboardsopen the passanger door and seek for under the sprint and you will see a black plastic duct with somewhat black steel strip and do away with the screw and then enable the filter out to drop downyou need to artwork it out something is uncomplicated
- Q: Welding of copper tube and stainless steel pipe, and welding by oxyacetylene welding? Specific steps please teachers advice.
- You can use argon arc welding, gas welding is very rare now.
- Q: how much water pressure can a copper pipe withstand?
- I believe common copper tubing is tested to 250 psi for plumbing systems. Certainly air pressure from compressors goes that high. Won't take hydraulic pressures (over 1000 psi)
- Q: I have held a battery operated AM-FM radio close to a non-grounded water pipe. I get a stronger signal near the left (26‘)and bottom (24‘) legs of the T but no signal near the right side(4.5‘). All sides of the T are running in horizontal plane.
- The 26' and 24' legs are closer to the wavelength that you are bringing in and thus work as an antenna.
