Why condenser is used in boiler or steam power plant?
A power plant of the conventional steam turbine/generator type, whether using fossil fuel or a nuclear reactor, operates by pumping feedwater at high pressure into the steam raising units, the steam is admitted to the turbine which has various stages. At the high pressure end the rotor blades are short but they get progressively longer as you go down the machine, because the steam is expanding to a lower pressure so has a greater volume. At the back end where the steam comes out of the turbine, you will get maximum power and hence maximum efficiency of the plant by having a vacuum, so that steam below 100 degC is still doing useful work. Hence the condenser cooled by ambient temperature water from an outside source, where the below atmospheric pressure steam is condensed to water and returned to the feed pump inlets. So you may see the condenser as wasting heat, but in fact it considerably increases the overall efficiency. This steam/water cycle is called the Rankine Cycle and you will find an article on this in Wikipedia.
What is deceleration measured in?
Deceleration means to decrease the velocity. The SI unit is the same as acceleration. In SI units, acceleration is measured in meters/second² (m·s-2).
What is the difference between Business Analysis and System Analysis?
Let's start by differentiating the role from the job title. Many organizations have Systems Analysts as a job title, but often the role of performing systems analysis is often assigned to employees with other job titles, like Architect, Business Analyst, Developer or, I even know a few companies where the person with the Project Manager title performs systems analysis activities.
Systems Analysis Role
For sake of making this easy to understand, let's focus only on the role, taking for granted that different organizations may create a formal Systems Analyst job title to perform all of the system analysis activities; or they may split these activities and shove them here and there with other job titles.
System Analysis activities focus around the translation of the business requirements into systems requirements. Business requirements have to be analyzed and decomposed into a series of smaller requirements for different components, providing directions for the engineering team.
Example
Let's say that the business requirement is to add a new optional "Where did you hear about us?" drop down on the Register page for a trade organization. Possible values are {"TV", "Radio", "Marc's List", "The New York Times", "The PMI Newsletter", and "Other"}
This would typically be written by the Business Analyst.
Systems analysis activities would decompose this requirement into:
- New fields or a new table required to capture the user's selections.
- A new table required to capture the drop down values.
- A change in the user interface to add the drop down control.
- etcetera
2 Aspects of System Analysis
The first step is to look at everything that is needed to make the new requirement work. Look at what is required in the database area, the local session information, the middleware layers, connectivity requirements, the user interface, or perhaps a new system interface, a new web service or something of the sort.
After analyzing what is required, the systems analyst must look into what can break if the requirement is implemented. This implies analyzing each and every system component to ensure compatibility, and that there are no conflicts.
The activities of the system analyst border those of the Business Analyst at the start of the analysis and those of the Architect towards the end of the analysis.
For modern SDLC methodologies (RUP, Agile, XP, EssUP, etc.) system analysis also defines the scope of the system under consideration and models requirements by taking the black box view and whitening it. (if this is obscure, stay tuned for an upcoming blog entry on black box versus white box.)
Should Analysis be performed by Analysts?
I have encountered several IT Managers who believe that analysis is not necessary. My answer to them: "Whether known or not, system analysis is performed somewhere in the organization. The question is... Is it done by the Analyst, the Architect, the Developer, or if not done before deployment, then, done after deployment when the defects are analyzed? It is, by far, less costly to have the Analyst perform system analysis."
Drinking water problem in rural area?
There is a great drinking water problem in rural areas because there are poor water piping and sewerage facilities. Many rural residents need to rely on traditional means of water collection and purification.
What are positive effects of a landfill?
landfills can be good because if we didnt have landfills there would be garbage all over our world.We need landfills to put all the garbage in.
Landfills can be bad because it can polute the air. the landfills put nitrogen in the ground and that isn't good.
What changes alternating current into direct current?
Yes but is somewhat complicated to get good level DC from an AC source.
================================
Answer #1.5 :
All electronic devices operate on DC ... radios, TVs, computers, stereos, etc.
If the device plugs into the wall outlet for power to operate, then the AC from
the wall outlet is used to produce DC internally to run the device.
Set a tool in a metal lathe at what angle?
Cutting tools for facing and outside diameter turning are set to an angle of 90 degrees to the bed. Boring tools are set to the same angle as the bed.
Cutting tool tips are already angled to suit its purpose and there's usually no need for further adjustment. They can be set against the inside of the toolpost and fastened.
What is the largest space station?
There is no current US space station. The last US space station was called SkyLab - but it entered Earth's atmosphere in 1979. The US (through NASA) currently uses the International Space Station or ISS.
cwt means carat weight total, often used when there are multiple gemstones. A pendant, for example may have 8 small gems of varying sizes that total 1/4 of a carat. So the total weight of gems is .25 carats.
Why are gases always stored in cylinders instead of rectangular containers?
Gases are stored at high pressures. A cylinder is very strong and uses less material than a box. The strongest container for the amount of material used is a sphere. The cylinder is a compromise that provides a good strength to material ratio with an easy to transport flat bottom.
What ingredients are needed for a star to form?
Stars cannot form, because all the stars were made in the beginning when God created the Heaven and the earth. A lot of stars have been see to blow up, called novas, and super novas if they're really big, but never, has one star been seen to form. An argument that has been used to claim that stars can form is that if 20 stars next to each other blow up, the the dust remnants of them can come together to form a brand new star. The problem with this is that, due to Boyles Gas Law, when dust in outer space comes together, it creates heat, and that causes the dust to move away again, so using this logic, stars cannot form from star dust, and if the dust could come together, you lose 20 stars to make just one new one, that is still losing, not gaining.
What are the financial factors in the design process?
Many things. Not only does a building need to be apealing to the eye, it has to be structurally sound. Snow loads, wind loads, high water areas all affect design. The type of construction to be used is always a factor (wood, steel, concrete, masonry)and all types of construction design will differ based on the material or combination of material used. Another big factor are the building code guidelines, and fire safety guidelines in effect in that area. I hope that helps you out somewhat.
Also you need a good site to build on...soil conditions need to be sound
Just to make it a little bit easier:
- Environmental - What impact on the environment during and after the work is done the build may have. If it may lead to destruction of habitats, contamination of soil and water.
- Time - How long it may take to finish the work
- Legal - Design must be made in accordance with building regulations. If the design doesn't add up with regulations must be rearanged and this may delayed whole work
- Financial - This factor should be calculated if the client has enough money to aford to pay for work of all people who would work for him. Access to bigger funds let the architect use expensive materials.
- Weather - Work might not be finished in time because of bad weather.
- Planing process - Building needs to be apealing to the eye, it has to be structurally sound. Also, must be considered the type of construction to be used (i.e. wood, steel, concrete, masonry) building load i.e. snow and wind loads.
Tool use to calibrate a micrometer?
Calibrating micrometers: For quick reference the supplied test piece can be used. For calibrating a micrometer, gauge blocks are used.
How are sound engineers and audio engineers different?
Mixing is a part of audio engineering. Mixing occurs after the recording process and before the mastering process. Recording, mixing, and mastering engineers are all audio engineers because they all deal with audio.
What materials - exact materials - and manufacturing processes are used in making a 3 pin plug?
The typical household plug is made from

odammit
overclocking
optocoupler
oxide
The purpose of the first "request for comments" (RFC) document that was published on April 7, 1969, was to allow engineers and others to discuss ideas, research, and methodologies in a public forum. Many consider this to be the "birth date of the Internet."
What is learning rate in neural network?
The learning rate is a constant in the algorithm of a neural network that affects the speed of learning. It will apply a smaller or larger proportion of the current adjustment to the previous weight. The higher the rate is set, the faster the network will learn, but if there is large variability in the input the network will not learn very well if at all.
