why is brass used to make taps?

I have three reasons -\n\n1. Brass is extremely resistant to corrosion due to its two main components. These are Copper and Zinc. Different grades of Brass are created by varying the levels of each component.\n\n2. The relatively low melting point (900–940 °C depending on composition) of brass and its flow characteristics make it a relatively easy material to cast. Hence ideal for fancy Taps!!!\n\n3.Its yellow colour, obviously similar to gold. It is relatively resistant to tarnishing. Although most modern taps will be plated with Chrome, Older Antique Brass Taps can be easily cleaned and polished to look like new.

Below is a link to a practical for finding the % copper in pennies.  The same method will work using brass in place of pennies.\n\nhttp://www.creative-chemistry.org.uk/alevel/module5/documents/N-ch5-17.pdf

Nobody actually knows where that phrase comes from.  There is an urban legend about where it came from that can be found here: http://www.snopes.com/language/stories/brass.htm

I know you can buy taps at the budweiser store in sea world.  try checking with a local beer dist.

You can use the valve oil and grease. You can occasionally run warm soapy water through it (being sure to rinse it all out). Do not dry it with anything abrasive. Most trumpet metal is very easily scraped. Please note :Paper towels are abrasive.

Depends on temperature and specific brass alloy.  Above 940 deg C, brass is a liquid.  Below that temperature, most brass alloys are solid.

Tap water.\nSoap breaks down the surface tension.

Simple. To avoid salt deposition on the cathode and anode. Simple tap water has many salts, whereas distilled water has a very less or negligible amount of salt. Answer is according to my logic. Need'nt be correct.

Hi:\n\nThey force molten metal through a specially made die. It the same way they make pipes. This die is as the following shape: it is a circular opening  with a circular block in the middle. When the molten metal is force through this form. the opening in the center forms  a air gap in the metal's center and the metal is rapidly cooled down to solidify it and is drawn way from it. it is stretched by hydraulic press until it is the right diameter to lenght\nand it is then cut to the right lenght and sharpen on a specially built machine made for it  and soak or rise with alcohol and assembled to the screw syringe needle holder or inserted to the bottom of a plastic syringe body for a disposable type syringe and that all there to it.

Generally speaking, lead was not used in the making of keys.  Lead tends to be too soft, even when alloyed.\n\nBrass, bronze and iron have all been used to make keys since the invention of the lock.  It the corrosion on the key looks green or blue, then the key is a copper alloy (brass or bronze is most likely).  If the key rusts, then it is iron or an iron alloy.\n\nThe only exception to this is the fact that ornamental keys have also been make for a long time.  Some of these may have been made with pewter, which is an alloy containing lead.

Trumpet, trombone, bass, baritone, French Horn...pretty much any brass instrument.

Firstly, the purer the water, the worse it is to use as a conductor. Mainly, the dissolved conductive elements we find in tapwater increase its conductivity, but are not as effective as say the ones found in saltwater. So, unless you wanted to spend the time and money to dissolve the copper, zinc, lead, and other conductive materials in water that could more easily be ducted into wire, it won't be a good idea.

To answer it simply chemical engineering is used almost in all engineering disciplines - whether it is process engineering, metallurgical uses or evaluation, corrosion engineering, chemical and pharmaceutical industry, food processing or food preservation, agriculture - pest control and pesticides etc.\n\nIt helps you achieve the right blend of properties to get the right kind of steel, stainless steel, brass, copper, aluminum, silver, gold and hundreds of other alloys that  are specifically made for certain applications to name a few.

Yes definitely! This is for the simple reason:-Tap water is likely to contain dissolved salts, and other impurities. But distilled water contains only water, and hence better.

It allows the ink to flow.  If not, the flowing ink would create a vacuum inside.  It the same principal with can of oil (i know this is going back but oil used to be in cans)  You poke a second hole to allow air to replace the oil so it can flow easier.

Hi. Usually to minimize pressure variations in a home's water system. Fire extinguishers, aerosol cans, Coleman stoves, etc. all use them to store potential energy.

With enough pressure any fluid may be used to creat domes, caps, ect in your sheet metals. By sing the same processes in deep drawing you could in theory use pressuized fluid by restraining the sides of your medal, but I would guess you might get irregular shapes by just applying this pressure randomly.\nIf you were to possibly use an iron (solid) stencil to say over the top of your sheet metal, then apply the pressurized fluid you might achieve the design in the stencil.\nThat's about all I can tell you, I'm not an engineer.
