Mechanical Engineering

Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

How do you calculate heat rate of steam turbine?

Heatrate is the term used in power industries to check how efficiently the plant is running. its unit is kilo calories per kilowatt hour..= Kcal/Kwh or in a shortcut method, the HR can be directly calculated by using the formula = Specific fuel consumption * Calorific value

Prime movers for power generating operation?

A "prime mover" is part of a generator - specificially the thing that's causing the generator to spin (such as a turbine). It is called the prime mover because it is what is causing the generator's rotation.

What type of gas is used in the blue cylinder that is installed together with the TIG machine for TIG welded?

That greatly depends on the type of steel you are welding, but you should be safe with a CO2 Argon mix, otherwise known as Steel mix, it is good for mild to medium grade steel.

What are the differences between corrugated steel and stainless steel?

Corrugated iron is the material used for roofing it is either Zinc coated or Zincalume coated the later is the modern version. Stainless steel is an alloy of steel and mainly nickel and far les likely to corrode then corrugated iron.

What is a rotap sieve shaker?

Rotap sieve shakers are used for laboratory testing of particle size and size distribution in samples of solid materials. Used for soils, geological materials, alloys, and a host of other solid sample types that have individual particle sizes of from over 5" down to 20 microns. Testing is accomplished by stacking a set of sieves of various sizes on top of each other, where the larger-hole sieves are on top and smaller-hole sieves are on bottom, in decreasing order. A solid pan is at the bottom to catch all sample particles that can pass through the smallest sieve's openings. The Rotap sive shaker is an apparatus that holds the entire stack of testing sieves, mechanically shaking/rotating them in a circular motion and tapping the top of the stack at the same time (this, Rotap). These actions help the various sized particles to be able to move through the stack of sieves until they rest on a sieve whose openings are too small for them to pass through. After a designated period of time of this mechanical shaking/tapping, the screens are removed from the Rotap, and each sieves contents are weighed up and recorded individually. From this data set, the % retained on each sieve is used to classify the size fractions present in the sample.

What is the average yearly salary of a pharmacutical rep?

The average yearly salary of a pharmaceutical representative varies depending on factors such as experience, location, and employer. On average, pharmaceutical representatives in the United States earn between $60,000 to $80,000 per year. Some may earn more through commissions and bonuses.

What is seem pipe?

What are the best cleats on astro turf?

There are two options to go with. I'm answering from experience with indoor turf playing paintball. There are several "Turf" cleats available whose bottom consists of tons of little spikes that grip well. Another not so well known option are athletic shoe style golf cleats. They offer very good grip but are difficult to find. Regular style golf shoes are built more like shoes and do not flex well. Either will offer excellent grip even with paint soaked turf.

Which is better a doctor or a engineering?

Assuming that you are capable of becoming any one of them, you need to figure out which one would make you happier. If more money would make you happier, then "doctor" would be a better choice, under the above assumptions.

3 Describe one important difference between the use of gases in pneumatic systems and the use of liquids in hydraulic systems?

Check your textbook. This is a question in the Grade 8 textbook. Page 325 to be exact. I'm trying to do the same question. :P

What is swirl ratio?

How much money does a civil engineer earn in Australia?

The average monthly income for a civil engineer working in Australia is 7,247 AUD. This is equal to $6,544.77 in US dollars.

What does 1714 mean in hydraulics?

ok....let us say we have one horspower.

So, we have 33 000 (ft.lb)/min = (1 psi * 1 gallon/min) * (a constant)

Again, we have 396 000 (in.lb)/min =(1lb/in^2) * (231 in^3)/min * (constant)

Now, if you cancel all the units y9ou end up with:

396 000 = 231 * Constant

And to make the equiation correct:

396 000/(231) =Constant = 1714

What are the old Russian units of measure?

"versta" = 3500 ft "sazhen" = 7 ft. "arshin" = 2ft 4 in. "lokot'" = 1 yard "vershok" = 1.75 in "duym" = 1 inch "pud" = 1 16,38 kg "funt" - 1 pound "gorst'" = a handful

What does 12 inch swing over bed mean for a wood turning lathe?

The diameter of the largest workpiece that can be rotated on the spindle without hitting the bed. This is the first of the two numbers used to describe the size of a metal lathe. In the case of the 7x10 or 7x12 lathes, it is 7".

How much did the lhc cost?

The BBC show titled "the six billion dollar experiment" announced that the LHC will be switched on in Oct, 2007. But the schedule has slipped a year to Oct, 2008. So I guess the total cost will be around 7 billion.
