piping network in series or parallel are suitable for distribution systems in Cities, commercial or resident?

I take it they won't allow you (for some unGodly reason) to tour your local water utility company, hence the reason for your question?? It's a shame but since that appears to be the case, i'll run it down for ya. All modern systems (unless designed by buffoons) are both, in series , parallel systems with built in redundencies to help isolate sectors with problems but yet still allow adequate & equal water distribution/pressure throughout; Why do you ask??

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.

It depends on the location of the transmission lines. The electrical power is usually brought to domestic consumers  at 11 kv or 11,000 volts and the same is brought down to 440 volts by transformers, for three phase distribution lines. To bigger industrial installations, the power may brought at 33 kilo volts also.  From generating power stations, the electricity is sometimes transported by upping it even to 400 kv sometimes. Higher voltage means lower current for the same power to be transported with a given cable which will cause less resistive heating i.e. less power loss in the transmission cables.

the quickest way to figure it out i think would be to call a fitting/valve supply house and ask them. the BSI standard you reference deals with manufacturing. i have found some ISO sets that govern this and some API but im not in India and have yet to build anything in that country so i doubt these will help. unless India uses American Petroleum Industry standards.

A butt weld is the most common for pipe to pipe connections. Depending on the size, pipe fittings normally are butt welds or socket welds. Smaller connections (2" and smaller more or less) can be socket weld (fillet) or butt welds. Larger than 2" (more or less) are typically butt weld. \n\nFor flanges, in addition to butt weld and socketweld, slip on flanges are also available. They usually require two fillet welds one on the inside and the other on the outside.

Star-delta systems, as they are known in Great Britain and Europe, (transformers, motor starters, line reactors, electrode boilers etc) are essentially the same as what America refers to as delta wye systems, the only difference being in geographic terminology. \nThe phrase refers to two connection methods of a device in a three-phase electrical system: an example would be a distribution transformer with a delta primary, running on three 11KV phases with no neutral or earth required, and a star (or wye) secondary providing three 240v phases and an earthed neutral point.

Tar is a non-conductor.\n\nMaterials for wiring interior electrical systems in buildings vary depending on:\n\nRating of the circuit \nType of occupancy of the building \nType of electrical system \nNational and local regulations \nConditions in which the wiring must operate. \n\nModern wiring materials:\nModern nonmetallic sheathed cables (NMC), like (US and Canadian) Type NM, consist of two to four thermoplastic insulated wires and a bare wire for grounding (bonding) surrounded by a flexible plastic jacket.\n\nRubber-like synthetic polymer insulation is used in industrial cables and power cables installed underground because of its superior moisture resistance.\n\nInsulated cables are rated by their allowable operating voltage and their maximum operating temperature at the conductor surface. A cable may carry multiple usage ratings for applications, for example, one rating for dry installations and another when exposed to moisture or oil.\n\nGenerally single conductor building wire in small sizes is solid wire, since the wiring is not required to be very flexible. Building wire conductors larger than #10AWG (or about 6 square millimetres) are stranded for flexibility during installation.\n\nIndustrial cables for power and control may contain many insulated conductors in an overall jacket, with helical tape steel or aluminum armor, or steel wire armor, and perhaps as well an overall PVC or lead jacket for protection from moisture and physical damage. Cables intended for very flexible service or in marine applications may be protected by woven bronze wires. Signal cables, such as Ethernet cables, that must be run in air-handling spaces (plenums) of office buildings may be required to be fire-resistant and made with Teflon or other materials that produce little toxic fumes or smoke.\n\nFor some industrial uses in steel mills and similar hot environments, no organic material gives satisfactory service. Cables insulated with compressed mica flakes are sometimes used. Another form of high-temperature cable is a mineral insulated cable, with individual conductors placed within a copper tube, and the space filled with magnesium oxide powder. The whole assembly is drawn down to smaller sizes, which compresses the powder. Such cables are fireproof and can be used up to 200 °C, but are costly to purchase and install, and have little flexibility.

i am assuming you are trying to minimize losses in a utility distribution system...when i was a system engineer at a utility..the quickest payback items were 1)correcting power factor as close to unity as possible with switched capacitor banks 2)have a policy of sizing distribution transfomers properly in relation to the load (i.e not oversized) to miminimize NL (no load) losses and not undersized too much either to minimize LL (load losses).\n3)size distribution feeder conductors to miminize both NL and LL losses.  The correct point at which you achieve max savings has a good bit to do with your %rate of capital as well as your cost of power both KW and KWH rates.

Check with local energy company. good luck

um....no.  We can't readily draw on here.  Second, how can we summarize our drawings, if we can't draw on here.  There are a lot of websites that talk about the 4 main network topologies.  I suggest you search for star, bus, token ring, mesh.

Yes if the sub station were the power comes from goes down, it won't make a difference where your lines are

I have a drawing that shows the various types of shell and tube exchangers. I believe their functions are self evident if you see the cross sectins.\n\nSend me you email address and I'll send the drawing.
