Industrial Engineering
Industrial Engineering is the branch of engineering that deals with the creation and management of systems that integrate people and materials and energy in productive ways. An industrial engineer studies industrial productivity and makes and implements recommended changes.

How much does builing a submarine cost?
The current-generation U.S.S. Virginia nuclear attack submarines cost between 1.8 and 2 billion dollars each, including the amortized development costs for designing the class (i.e. it costs about 1.4 billion or so to actually build the sub, but there were several billion in startup, R&D, and design costs for the class, which adds about .5 billion to each sub).
A typical non-nuclear attack submarine (such as the German Type 212) costs around $500 million, including the amortized development costs. Note that the typical non-nuclear attack submarine is usually about half the size (and a quarter of the displacement) of a nuclear attack sub.
How cooling tower height is significant for cooling tower design?
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
What is TOPSIS method in Multi-criteria Decision making?
it stand for Technique For Order preference BY Similarity to Ideal Situation
The principle behind TOPSIS is simple: The chosen alternative should be as close to the ideal solution as possible and as far from the negative-ideal solution as possible. The ideal solution is formed as a composite of the best performance values exhibited (in the decision matrix) by any alternative for each attribute. The negative-ideal solution is the composite of the worst performance values. Proximity to each of these performance poles is measured in the Euclidean sense (e.g., square root of the sum of the squared distances along each axis in the "attribute space"), with
optional weighting of each attribute.
Some of the more common ones are soda-lime glass (window glass), Wheeling (moldable) glass, borosilicate glass (Pyrex), and quartz (hard) glasses.
Your question doesn't make it clear if you're thinking of types in an industrial, architectural, or technical sense.
Should a 24vdc circuit create arcing to use as a switch or signal?
Some voltage must be present but the current causes the arcing.
What are the uses of a belt drive?
A belt drive is an alternative to a chain drive (as you would normally find on a bicycle or motorcycle). There are several types of belt used in belt drive systems including V-belts and toothed belts. The more common is the V-belt. A cross section of the pulley used shows that the belt runs in a V-shaped groove. Washing machines, older cars, and machinery use this type of belt system. The toothed belt is normally wide and flat with teeth on the inside to prevent slippage. Harley Davidson motorcycles use these, as do super-charged engines in cars.

Why have so many variable type devices in autos been replaced with attribute type devices?
Inspection of items or products can be done in two ways:
1. By attributes, using gages to determine if the product is good or bad, resulting in a yes/no, go/no-go decision.
2. By variables, using calibrated instruments to determine the actual dimensions of the product for comparison with the size desired.
In an automobile, a speedometer and oil pressure gage are variable types of measuring instruments, and an oil pressure light is an attributes-type of gage. As is typical of an attributes gage, the driver does not know what the pressure actually is if the light goes on, only that it is not good.
Variable types of inspection generally take more time and are more expensive than attribute inspection, but they yield more information because the magnitude of the characteristic is known in some standard unit of measurement.
How do you calculate the excess inventory across a supply chain or at a particular site warehouse?
You would have to do a count of all the inventory. Have all the managers submit the information so you can determine the excess.
What makes the fluid flow in a pressurized system?
a difference in pressure (differential pressure). For example putting air in a tire (I know its pneumatics and not hydraulics but it is the same concepts.) the air tank is holding 110 lbs of pressure and when you connect the hose to a tire with 25 lbs the air is going to flow from the tank to the tire. or from high pressure to low pressure.
How do you wire a Bridgeport Mill running on 440 3ph to 240 3ph?
Hi there are a few options. The one I chose was to use a VFD (variable frequency drive). First though if you want to run off true lower voltage you will need to check that the motors can be reconfigured to run as delta instead of star. If you look at the motor plate this should give you some idea. If you are lucky the motor terminals will have links that let you move them to reconfigure. If not you will have to research further on the net. If you use a vfd instead of a rotary or static inverter then you will have to connect the output of this directly to the motor ie with no switches in between. All the control like forward, reverse etc are them controlled as low voltage inputs to the inverter. With a rotary or static inverter it is possible to feed the output of these inverters to the supply of the existing wiring but motor voltages and contractors may not work on the reduced supply.
