Mild steel, not copper.

To know the force, you need to know how much you want to bend it; you also need to know the dimensions of the plate and how it is supported.

The primary benefit of the Aswan High Dam was electricity generation, which allowed Egypt to be a modern country. Secondary benefits included preventing the yearly floods of the Nile and keeping a reserve of freshwater, should Egypt have a drought.

An electric iron consist of basically a heating coil and heat control circuit viz thermostat. Thermostat act as a switch. When we switch on the electric iron current flows throught the heating coil. The heat in the heating coil causes expansion in the thermostat which gradually disconnects the supply. [ see the working of thermostat].

In simple terms: think about the amount of physical trauma caused by getting hit by a car going 60 miles per hour. Now take the velocity of a car, and make it a LOT bigger. Now take the impact area and make it about several thousand times smaller.

That's an a greater amount of kinetic energy than a speeding car, impacting on a much small area. It shouldn't be hard to figure out why the physical damage of a bullet, if well placed, can easily kill someone.

and an even more simple term: bullets make holes. The person dies either because they bleed to death or because the bullet damages something vital like the heart, or a combination of both.

Here are some examples of iron; pig iron, cast iron, wrought iron, ingot iron, enamelling iron, gray iron, white iron chilled iron, malleable iron, ductile iron, compacted graphite iron, alloy iron, abrasion-resistant iron, corrosion-resistant iron heat-resistant iron

Steel is a relatively cheap metal to sell and you would need a lot of it to get a large profit. The price of steel varies depending on the current market. Contacting a local scrap yard would be the best way to know the current rate.

It is the term used by fundamentalist Christian protestants for the religious belief that the creation story in Genesis in the Bible is literal truth. They like to refer to this as a "scientific" theory, but since they can make no verifiable claims about the world from the theory, it is not.

What these people do not realize is that the Bible is an allegory, and its stories teach ways to be a better person. One can have faith and not also believe that the universe was created in a literal 6 days.

I guess it's the strongest form of structure to form the end of the upright cylinder which is the basic reactor enclosure. The reactor must be enclosed with a structure which can contain the worst type of reactor failure which would release a lot of steam. It also protects the reactor and its equipment from the weather.

Compounds of metals, steel and other materials that the alloy is known. It is pure iron.

'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.

There are several reasons why chemistry has such a high importance in electrical engineering. It is important because chemistry helps you to know more about the materials you are using and working with. Knowledge of how materials and products work together is needed in the engineering field.

I've spent a few years involved in the specification and requisitioning of a large (10 000+ I/O) Honeywell DCS, and before that I spent 2 years doing the same for a large yokogawa DCS.

When it came to both the hardware performance/capability and the quality of engineering, there is no comparison, Yokogawa won by a long way. I can't comment on price.

A few gripes I've had with Honeywell:

1) Inter-plant signals - signals had to be hardwired between controllers if they are to be passed from one community/domain to another to maintain a scan rate of 1 second. Sort of takes word 'distributed' out of DCS.

2) Graphics are very limited in the number of tags/variables and many of them had to be split up - much to the operators dismay.

3) Sheer volume of unnecessary documentation - for example, they submitted a 50 page document for review describing the typical software for a differential pressure indication.

The industry has changed a lot of the past few years especially with increased pressure for good resources so I'm sure all DCS vendors are subjected to the same engineering quality problems. Therefore will not go into the engineering issues we had.

Hope that helps.

I am not fully agree with the above explaination. You may be a Yokogawa supporter, but don't just give false information to other.

1) Inter plant connectivity can be achieved through DSA (Distributed Server Architecture) configuration.

2) Graphics are built for man-machine interface only. Off course, if you want the whole plant to be in one graphic page then that's create performance issue. If you built and arrange your graphic pages properly, there should not be any issue raised.

3) Nobody will agree that 50pages are submitted for a pressure loop description. I have seen SDM (Software Design Manual) from Honeywell used for a particular project. It was nice and explanatory.

---------------------------

The one u said on the new Honeywell DCS ... EPKS ....

I am using Honeywell for a long time.... but as a customer we are looking at the work quality

and products ..... I am not sure about Yokogawa but I believe it does have similar problem like Honeywell...

Products problem:

1. Too many bugs

2. No experties in Malaysia for new products

3. SUpport team lack of compentency

4. Product reliability and availability weak...

and all of this contribute more cost to customer where they had to pay them just to fixing things that they also not really expert...

this the reason why user keep asking and concern on the cost for them to repair.

anyway .. both system has their own weakness... so the only ways is how we ensure they

deliver the good quality one..

A bachelor's degree in most areas can require between 124 to 128 college credits particular to a specific program of study. This would be based on a college or university that operates on a regular two semester academic year which is the most common. For institutions that operate on a tri-semester or quarter-semester it would be quite different. That being said, the Bachelor's degree - in most cases - is designed as a four year program of study, provided the student is full-time and follows their chosen program of study as prescribed by the college or university, and also provided the individual does not require prerequisite or developmental coursework as a result of basic skills testing. The minimum credit load for a full-time student is no less than 12 credits per semester. However, to complete the degree within the four years, a credit load of approximately 15 to 18 credits is recommended. For individuals who work or who have other responsibilities that would prohibit them from attending full-time, completion of the degree may take twice as long. Still, some of this time can be cut down by attending summer sessions and/or interim sessions. In addition, the bachelors and associate degrees are referred to as undergraduate degrees while the masters and doctorate degrees referred to as graduate degrees.

First of all

frp full form is glass reinforce plastic and

grp full form is glass reinforce polyester

the difference between this two is,grp is one of the type of frp pipes

like other types are grv (glass reinforce venylester)and gre (glass reinforce epoxy) depends on type of resin(chemical) to be used to make frp pipe.

There is not a straight forward answer to this question. Basically the strengths of mild steels depends on its material composition. All steels are made with varying alloys and are made from different processes eg. casting, hot or cold rolling and they all have a different effect on its strength. If you know the specifications of the mild steel you are using there are tables for which you can obtain these values. Typically I have seen the yield stress vary from 250 MPa to as much as 550MPa, so you can have an idea of just how much they vary based on their composition.

High frequency of electricity is passed through a coil and is most often used in steel alloys. The amount of heat and the size of the coil will help to determine the amount of time needed for the project being undertaken.

A pneumatic actuator converts energy (in the form of compressed air, typically) into motion. The motion can be rotary or linear, depending on the type of actuator. Some types of pneumatic actuators include: * Tie rod cylinders * Rotary actuators * Grippers * Rodless actuators with magnetic linkage or rotary cyclinders * Rodless actuators with mechanical linkage * Pneumatic artificial muscles * Speciality actuators that combine rotary and linear motion--frequently used for clamping operations * Vacuum generators A Pneumatic actuator mainly consists of a piston, a cylinder, and valves or ports. The piston is covered by a diaphragm, or seal, which keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm downard, moving the piston underneath, which in turn moves the valve stem, which is linked to the internal parts of the actuator. Pneumatic actuators may only have one spot for a signal input, top or bottom, depending on action required. Valves require little pressure to operate and usually double or triple the input force. The larger the size of the piston, the larger the output pressure can be. Having a larger piston can also be good if air supply is low, allowing the same forces with less input. These pressures are large enough to crush object in the pipe. On 100 kPa input, you could lift a small car (upwards 1,000 lbs) easily, and this is only a basic, small pneumatic valve. However, the resulting forces required of the stem would be too great and cause the valve stem to fail. This pressure is transferred to the valve stem, which is hooked up to either the valve plug (see plug valve), butterfly valve etc. Larger forces are required in high pressure or high flow pipelines to allow the valve to overcome these forces, and allow it to move the valves moving parts to control the material flowing inside. Valves input pressure is the "control signal." This can come from a variety of measuring devices, and each different pressure is a different set point for a valve. A typical standard signal is 20-100 kPa. For example, a valve could be controlling the pressure in a vessel which has a constant out-flow, and a varied in-flow (varied by the actuator and valve). A pressure transmitter will monitor the pressure in the vessel and transmit a signal from 20-100 kPa. 20 kPa means there is no pressure, 100 kPa means there is full range pressure (can be varied by the transmiters calibration points). As the pressure rises in the vessel, the output of the transmitter rises, this increase in pressure is sent to the valve, which causes the valve to stroke downard, and start closing the valve, decreasing flow into the vessel, reducing the pressure in the vessel as excess pressure is evacuated through the out flow. This is called a direct acting process. http://en.wikipedia.org/wiki/Pneumatic_actuator

Ultimate shear stress of Mild steel is 210N/sq mm

pickary

this burns alot like gunpowder and gives a very similar effect. what you need is -powder fertilizer read ingredients make sure it has kno3 in it - suger mix it together with a ratio of one part suger to two parts fertilizer this will go bang like nothing you done ever seen. have fun =p

to protect the source from overloading a switch can be opened as a circuit breaker, fuse, overload protection schemes
