The application of scientific knowledge for a practical purpose is called engineering?

Yes, this is correct!The application of scientific knowledge for practical purposes is engineering.

4 What problems could result from incorrectly converting measurements from one system to another?

The worst kinds of failures could result. For instance, an air tank to be designed to hold 40 cu. ft. of compressed air at 300 psi, if the conversion were incorrect and the thickness of the tank actually built will only hold 100 psi safely, then the tank could rupture catastrophically while in use, killing or maiming anyone within 25 to 50 feet of that tank. Sounds extreme but it is a possibility.

What is the difference between ANSI flanges and DIN flanges?

The most obvious difference is that the standards for each are from different "worlds" so they are expressed in different engineering units of measurement.

Because of the above, the fundamental physical properties of the materials used to make the flanges may or may not be the same. Then, because of both of the above conditions the resulting size, shape and fit of the resultant fitting may - or may not fit together. And, even if they do fit (by coincidence) there is no engineering basis to assume that the resultant joint (which is why the flange is there in the first place) will behave in any predictable way.

Without a systematic empirical test, to use flanges from two different domains, join them together and then pressurize the system is like tossing the dice in a game of chance. What engineer is going to take this chance. What insurance company will cover the accident?

What is the vapor compression cycle?

the vapor compression cycle is the cycle used in the process of the refrigerator. for more info go to www.wikipedia.com . thanx for asking ur questions!!!!! ~tammie

Is it possible to do maths literacy and still do chemical engineering?

no you need matematics to do chemical engineering because of the formular wich involves maths not mathematical litrecy

How does CAD benefit society?

We use cad to make our work easier

Importance of pace factor for engineers?

when you don't have any device (such as tape, stadia, & etc.), you can measure a distance by your own pace factor....

Why a sweptback wing is better suited to supersonic flight than straight wing design?

because sweptback wings are less curved than normal rectangular wings and the shockwaves that form at supersonic flight form on curved surfaces, the less curved surfaces on sweptback wings make the shockwave form for a shorter time increasing the mach critical number and reducing drag a lot. genius

Are dams expensive?

Yes, dams are very expensive, and also very time consuming.

What are the criteria for synchronization of a generator with the grid?

  1. Voltages match
  2. In phase
  3. Generator should be spinning slightly faster than the synchronous speed of the grid

The second and third criteria are typically measured by a Synchroscope - see http://en.wikipedia.org/wiki/Synchroscope

What is a type of engineering in which genes are custom assembled?

Gene PCR(Polymerase chain reaction) Function-Makes copies of specific regions of sequenced DNA. Application-Used to copy DNA for any scientific investigation including forensic analysis, and medical testing. I do not know if this is right, but I found this in my biology book.

Do elevators have gears?

Yes. How do you think they run?

With a centrifugal pump what will a blockage in the discharge or suction side do to the pump amps?

A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.

What is composition of clay?

Clays are hydrous aluminum silicates with trace amounts of other elements like calcium, iron, and magnesium.
