Mechanical Engineering

A Knife Gate Valve is used to slice through sludge /sewerage and a gate is used fro normal positive shut off

It is the strength in pounds per square inch of a material at which it will be pulled apart.

staisteel is made of a mixture of iron and nickel and chromium

Fatigue life is the number of cycles a structure part can take before it breaks. A cycle is when the stress reverses or changes about its mean value as happens during vibration for example. Usually fatigue life is expressed in number of cycles; for example a steel part of a given strength may have its strength reduced in half after 1,000,000 cycles due to fatigue.

The last aim of a mechanical engineer is that the customer satisfaction and the efficient work

Industrial lubricants.

From 43,000 to over 90,000, depending on the dept of sonography and location of employment...

anywhere from $44,000 to $100,000 depending on the type of sonography

Like everything else, it's worth whatever someone is willing to pay for it.

In excellent condition with lots of 'tooling' like chucks, rests, attachments, extra parts, etc. a nice clean Wards lathe might be worth $1000 or more.

A rusty, dirty, neglected or abused old example with no extras and in poor condition?

Maybe a hundred bucks......maybe less.

There is absolutely no limit. The average salary of a doctor can range from $150,000 for a general doctor, $163,000 for a psychiatrist and $255,000 for a general surgeon. Regular doctors are not likely to earn more than this, but entrepreneurs can earn millions. This means doctors who, for example, instead of treating patients, invent a new drug or invent something that can be used by other doctors. But only a very small number of doctors do this. Here is a good article about the salary of normal doctors: http://hypertextbook.com/facts/2004/TiffanyYam.shtml -DJ Craig

calorifier contains the number of coils through which steam flows.

Steam from steam boiler goes to kitchen,laundry and for calorifier.Around these steam coils,water is flowing which needs to be heated. as u know temp of steam would be more than 100 deg,it heats the water which comes in contact with these coils .

in most of the calorifiers,a set point mechanism is fitted which cuts the flow of steam whenrequired temp of water has attained

A factor of safety against yield is applied to design stress

Yield Stress/ Design Stress = Factor of safety

The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems

Some stainless steel is non magnetic, like the 300 series which contains a good bit of nickel which makes this series non-magnetic, but the 400 series does not have nickel and are thus magnetic, so you cannot differentiate between this series of stainless and regular carbon steel using a magnet. If the sample in question rusts easily, then it's probably regular carbon steel, though there are some high carbon steels like D2 tool steel for example, which have a high enough percentage of chromium (D2 has 11% to 13% generally) which make them 'almost' stainless and thus they don't rust as easily as a high carbon steel like O1, which does not have enough chromium (.50%) too inhibit oxidation and thus it rusts quite easily. The only other means to tell whether you have stainless steel or regular carbon steel would be by performing a spark test which could tell you whether you have stainless or regular carbon steel or sending a sample out for metallurgical analysis.

what about electronics & telecommunication?

I my opinion electrical is best!

There are 4 they are Low Carbon steel, Medium Carbon Steel, High Carbon Steel and Eutectiod

Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.

Gate valve is basically created for an on-off service, it is designed to control the pressure drop and allow the passage of a pipe-cleaning pig. Gate valve can be also called as knife valve or slide valve.

you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy. you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy.

bRO , FIRSTLY , IF YOU LIKE DESIGN ENGINEERING THEN YOU CAN YOURSELF CRAVE OUT IT'S SCOPE. IT WOULD BE A LOT BIGGER DETAILED MESS , IF I STARTED HERE ABOUT IT'S SCOPE AREAS. BUT TO CUT IT SHORT , I WOULD SAY THAT, THE SHAPE OF THE WORLD AS YOU SEE IT IS OWNED TO THE DESIGN ENGINEERING. IT CHANGES THE WAY YOU LOOK AT THINGS , SO IF YOU THINK YOU HAVE COUPLE OF AWESOME IDEAS TO CHANGE THINGS AROUND YOU. BELIEVE ME, YOU WILL CREATE SCOPE YOURSELF, WITHOUT LOOKING OR EXPECTING FROM MARKET TREND. nEVER RELY ON , WHAT'S OUTSIDE , ALWAYS LOOK WHAT YOU CAN PUT FORWARD,

UPVC stands for Unplasticized Polyvinyl Chloride. It's a type of rigid and chemically resistant plastic used extensively in the construction of pipe installations and other infrastructural applications due to its durability, low cost, and resistance to water corrosion.
