Why petrol engines are used for light duty purpose and diesel engines for heavy duty purpose?

In simple terms, the petrol ("gasoline") contains fewer calories/btus per unit, so it can't do as much work as an equivilent amount of diesel. Diesel, being heavier, is more energy-dense, therefore capable of doing more work. More energy per unit means more work, and that translates into more a more valuable product, which is why diesel costs more than petrol.

Who do you call when you have a new invention?

what is your dream come true for this invention?

if you care to protect your rights of ownership you may wish to contact

* an independent, licensed patent agent

and

* an attorney who is an expert in patent law

if you wish to let people know about it you can contact a public relations person

if you wish to get people to help you make a business of it and you need financial help,

you may want to present your ideas to venture capitalist groups

but beware, if you invention is a "success",

in exchange for financing, they the venture capitalists will likely keep the lion's share of profit

if your stuck after these answers, i'd be willing to talk to you to get you to the right people. rob kanzer, life and business coach (www.robkanzer.com)

What is a common engineering problem with all big machines?

They have to be fixed up when they break and cost a lot of money.

What is interperation?

It is a typographical error.

I would not wish to make a guess as to what you meant to type. So please use a spell-checker and resubmit your question. If possible, include some context as well.

How do you install a metal oxide varistor?

A varistor is installed onto the "line" and "Neutral" wires of an AC power input.

Maybe this will help you more: cf. Related links, just below this answer page.

Why is it important for engineers to document all calculation?

Documentation is important so that they, and others, can review their work.

So that errors can be corrected without having to start over.

Technology clients won't buy inovative work without this type of information about the information or product.

How to conduct holiday test of piping?

Holiday test or a Continuity test is one of the non destructive test method applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids.

The test involves checking of an electric circuit to see if current flows to complete the electrical circuit.

A Holiday test or Continuity test is performed by applying low voltage (connected in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path.

If the electrical flow is detected then the test area is termed as conductive indicating presence of discontinuities such as pinholes and voids.

This test is commonly used in the offshore industries where piping and structures are coated with nonconductor coatings.

What is BOP of power plant?

bop means Balance of Plant. it includes Cooling tower, CWPs, ACWPs, Compressors, CHP,AHP, LDO pumps etc

What is parity generation?

Add up all the bits in a "word" - usually in 7 bits of an 8 but byte, and use the top bit in the byte to store the result. If there is an even number of bits set, the "parity bit" is 0, and if it is odd, the "parity bit" should be 1.

Electronic circuits can easily be made that generates this on say a COM port, that transmits one bit at a time and makes it possible to detect errors in the communication. It is also used in RAM memory - also to identify faulty memory chips. On disks they use more than 1 bit, and will here call it "ECC" - "Error Correction Circuitry". This is based on 3 bits that enables reconstructing the byte, not just detect an error.

Dense storage and fast transmission is always a trade-off with the correct stored data or data transmitted. Where the errors can be corrected without reducing capacity this is used.

Does adding spray paint affect a bottle rocket?

Certain kinds of spray paint will eat away at the bottle itself making it explode when it launches find non-petroleum based paints.

Why we don't use milling machine as driiling machine?

Although a milling machine is capable of drilling, it can be more productively achieved on a drill press or radial arm drill. Due to the complexity of the milling machine's function and the cost of its operation, it would not be feasible to use it for drilling. There are exceptions where using the milling machine for drilling a workpiece might be a better option.

Why did Michael Faraday invent Dynamo?

I think that Michael Faraday invented the dynamo(electronic generator) because people needed electricity to see in the dark at night & use electronic Things.

One history programs told how electricity was discovered and devices built to produce it but no one knew what to do with it. So, it became a like a play thing for rich people at parties and such. Seriously. It is similar to the demonstrations that they give at High Schools to amaze the students.

Is the inverted image created by a lens also inverted horizontally?

For a convex lens, if you trace out the path of the rays as they are refracted through the lens, you'll see that the inverted image gets reversed horizontally as well as vertically (in other words, the "inverted" image is really a 180 degree rotation about the axis through the center of the lens).

Why must efficiency be calculated and understood during the design process?

So you can account for any problems that may occur while building the object.

Advantages of tissue culture?

using tissue culture many plant can be grown from one parent in disease free condition

How to avoid surface concavity in autogeneous welding?

Do you mean your beads are concave and you would like them convex in appearance while autogenous welding is being done? Without knowing what metal you are welding or seeing the technique used I can only offer generalizations. It could be a lack of sufficient sulfur or improper travel speed. Without more info I'm only guessing.Which isn't good when it comes to welding.

How do you design irrigation canal using manning formula?

The manning formula is used to size the irrigation canal or any hydraulic section. Water may be transmitted from the source to the field by unlined or lined canal, pipeline or combination. The Manning formula relates the transmission media (the cross section area and resistance to flow) to the flow characteristics ie volume Q.

What grades in GCE Alevel are necessary to get full scholarship in aerospace engineering in best universities?

All 'A's. or all with the exception of a B. Make sure your maths and sciences are strong. Also your ECs should preferably involve some science background.
