What should be the transformer to building separation distance for fire suppression?
Depends on size of transformer and type (dry,mineral oil, silicone) as well as ground slope and building construction.
What is the function of Bypass diode in the test terminals of a pressure transmitter?
The function of the bypass diode is to allow the loop current to be measured without disconnecting the current loop connections. It therefore allows for a quick measurement of the loop current without disturbing any control or monitoring equipment that is connected to it.
This is achieved by simply connecting an ammeter across the diode. If the voltage drop across the ammeter is less than that of the diode (about 0.6V) then all of the loop current will flow through the ammeter rather than the diode. The ammeter is therefore able to measure the loop current.
What are all the ME courses in electronics and communication engg?
Mechanical engineering is a completely different discipline to electronic or communication engineering.
Though some aspects of mechanical engineering will be required in both at some time they will be tailored to fit the course you are taking.
What are the applications of vector fields in chemical engineering?
The applications are in transport phenomena, in determining the direction of flow in momentum transport, heat transfer, and mass flux.
"P I" might refer to the number "pi", which is approximately 3.1416."R" might refer to the radius of a circle.
For example, the circumference of a circle is equal to pi x diameter, which is the same as 2 x pi x radius.

There are several different types of handguns.
Single-Shot Pistol - pre-1840's design. Single ShotEarly guns were single-shot pistols that were loaded from the muzzle end. Black powder was poured into the barrel and the bullet forced on top of the powder. A Flintlock pistol was fired using a hammer that held a flint rock that fell against a Frizzen that created sparks. The hammer would force the frizzen away to expose the powder to the sparks. Revolver PistolThe Revolver was designed to allow the user to load 6 shots or more. The gun operates by rotating the cylinder containing the loaded rounds in individual Chambers. By pulling back the hammer (i.e. cocking the gun), the hammer moves a ratchet that rotates the Cylinder to a unfired chamber. This mechanism was copied from the windless of a ship. The gun is fired by pulling the trigger, thus releasing the hammer, allowing it to fall on the chamber to fire the bullet. Automatic PistolVery complicated mechanism. The gun has a slide mechanism that is pulled back and picks up a new bullet from the magazine in the grip of the gun. When the slide returned, it would cock the gun so that it would fire when the trigger is pulled.What is Effect of cerium oxide on fuel?
The cerium oxide is inert. The point when it becomes interesting is at higher temperatures when it can oxidize carbon for example at temperature much lower than the carbon will usually burn. Another useful property is that it will reduce nitrogen oxides and take the oxygen to form its ceric oxide state. This is used in car catalysts due to good efficiency and favorable price. Yet another use - which can be derived from wikipedia information already is chemical reaction with laughing gas - N2O to form really strong, orange oxidiser (NH4)2Ce(NO3)6 - ceric ammonium nitrate. I plan to test it in a rocket engine fuel soon.
Just to note - many combustion processes, whether in furnace, cars, rockets can not be enhanced, taken more power from them, because of the limited speed of reaction. That is where catalysts take place. Ceric oxide can act as a catalyst. When reacted with certain nitrous oxides it can take form of another chemical composition which acts as a strong oxidiser potentially increasing the speed of the reaction even further.
It is said that the east German racers used ceric oxide fuel additive to improve combustion of their vehicles on some races and thus cheated, but closer information on their setup is hard to find. In general ceric oxide will improve combustion if the combustion has tendency to form carbon particles, like in diesel engines or race engines with high fuel:air ratio.
The maximum surface area of ceric oxide nano-powders ranges from 35-70 square meters per gram of the powder. Ordinary polishing powders do not have such large surface area since they are aimed for polishing, not as a catalyst.

Why you need the differential equation in the field of engineering science and technology?
You need differential equations and partial differential equations to describe and predict the dynamic behaviour of systems. Newton and Laplace developed differential equations originally and simultaneously (using different notation) to work with gravity and the movement of the moon and planets.
What are components of a technological system?
iolo technologies is the world-leaderin PC tune up and optimization software including System Mechanic, Phoenix 360, Privacy Guardian, System Shield, Search & Recovery, Drive Scrubber, System Checkup & more!

If you want to gain IT skills and experience then you can join or apply to some BPO firms.
It depends on which type of IT skills you want,If you want IT skills in programming then i don't think BPO is the best place for you.
Relationship between operating system and windows?
It's blurred (intentionally, by Microsoft).
An operating system is the program that allows the computer to communicate with all its parts.
Windows is a GUI (graphic user interface) that "allows" humans to operate a computer.
Believe it or not, under the pretty pictures, (and that long pause after you turn it on),
your computer is still running DOS (or MSDOS : Microsoft disk operating system)
What is joint application development in system analysis and design?
Joint Application Design (JAD) was developed by Chuck Morris of IBM Raleigh and Tony Crawford of IBM Toronto in the late 1970's. JAD is a process used in the (SDLC) to collect business requirements(needs of customer/Problem definition) while developing new system for a company. "The JAD process also includes approaches for enhancing user participation, expediting development, and improving the quality of specifications." It consists of a workshop where "knowledge workers and IT specialists meet, sometimes for several days, to define and review the business requirements for the system.
How much weight can a LEGO bridge hold?
4.3 Lbs. That's based on the length/width of the deck being no more than 6". A suspension bridge will support more... Go find some string!
Difference between asymmetric and symmetric multiprocessing and simple multiprocessors?
A symmetric multiprocessing (SMP) system is one in which each processor runs an identical copy of the operating system on each processor. In an asymmetric multiprocessing, system, each processor is assigned a specific tasks. An example of this would be a master- slave relationship between one processor and “the rest”.
Is there really a need for more advanced technologies?
Technologies are what humans use to survive. Better technologies usually offer better means of survival and/or greater comfort in our daily lives.
There are always cost/benefit issues with the introduction of any new technology, but need or not humans will always pursue the creation of new and "better" technologies: we create technologies and our technologies create us anew.
How do you use WINDOWS system32 cmd exe for windows xp PC?
cmd.exe allows you to use command line for virtually whatever you want. You can use ipconfig command if you want to see information about your network adapters.
Start->Run->cmd, press Enter. type in the cmd window ipconfig.
Most of the common commands used are for navigating the file system, it is possible to do some harm to the system if the commands are not executed correctly.
There is hundereds of commands and programs that run within the CMD shell.
This link has a complete list of commands http://www.kapcom.com.au/Windows-CMD-Commands-CMD-Network-Commands.html
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
Difference between primary and extended partitions?
Primary Partitions are logical areas on Coputer storage devices that have direct reference in Master Boot Record. (Due to limitation imposed by MBR only four primary partitions can be created).
While Extended partitions refer to logical areas created out of need for more than four Partitions.
