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.

Yes, it is easily 'workable'. hence the name mild steel..
Why martensite is so hard and brittle?
For two reasons: 1. martensite is bct structure which prevent the movement of dislocations. 2. martensite has higher carbon concentraton.
Why the machining of brittle material is easy than ductile material?
Very ductile material will often smear rather than cut during machining operations. Less ductile material (more brittle) will cut more easily.
What are Procedures for reporting lost or damages documents?
Contact the issuer of the Documents and work with them to replace the documents
Is a filtration device for removing water from lubricating oil.
What is the difference between the shaper and planer and slotter?
A shaper is a reciprocating machine tool in which the ram moves the cutting towel backwards and forwards. A shaper is intended to produce flat surfaces. A planer is used to produce horizontal, vertical or inclined flat surfaces. A planer is used to work on heavy and large work pieces that cannot be accommodated on the table of a shaper. A slotter is also called a vertical shaper. The difference between a shaper and a slotter is the direction of the cutting action of the tools.
Is krypton a transition metal?
No it is not.Krypton is a chemical element with the symbol Krand atomic number 36. It is a member of Group 18 and Period 4 elements. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere, is isolated by fractionally distilling liquified air, and is often used with other rare gases in fluorescent lamps. Krypton is inert for most practical purposes.
Krypton, like the other noble gases, can be used in lighting and photography
Au stands for aurum, the Latin word for gold.
AU also stands for astronomical unit, the distance between Earth and the Sun (about 93 million miles long).
What is the function of a Saw Blade Sharpening Machine?
A saw blade sharpening machine is used for sharpening the saw blade. Nowadays, the advantages of a saw blade sharpening machine includes the adjustment rod arrangement- the reasonable arrangement of rod makes the operator easily to adjust the tooth cutting angle , the backlash angle, tooth depth and tooth pitch. Furthermore, the thickness adjustment of saw blade, which obtained patent in many countries, that the blade was hold by two moving devices at the same time and move to the central of the machine for grinding; thus, there is no requirement to manually adjust the thickness of the blade. And it also can reduce the grinding noise.
Take SU-850 (which made by Eyan Co., Ltd - www.eyan.com) for example, it has a Continuously Variable Speed Drilling function. By using the converter to control the grinding speed, it can adjust the required grinding speed according to the tooth pitch difference.
Today, Saw Blade Sharpening Machine uses computer to simulate and design the professional tooth profile cam in order to make the grinding simpler, faster and more accurate.
What is the difference between PS and PP?
Polypropylene (PP) is a good choice for product packaging because it is a highly durable material in both container and closure forms. PP is a good barrier against moisture, oil, and alcohol and it is resistant to many chemicals. The shortage of PP material lies in: it is easy to get oxidized and aged.
Polystyrene (PS) material is non-toxic by itself, but in the production of disposable tablewares, a lot of prohibited additives will be added into this material. And such kind of additives will dissolve with water, vinegar, oil and other things in the food. These dissolved material will go into human body, resulting in bad indigestion, partial ache and other kinds of diseases. That is why some areas have prohibited the usage of PS material in the industry of food packaging.
Polyethylene terephthalate (PET), a common plastic material known for its characteristic of durability, is capable of preserving a product's original aroma and taste. In comparison to the traditional PS cups, the PET material cups are more durable, stronger, transparent, chemical-resistant and crack-resistant. It is widely used as environmental-friendly material.
Apparent boost in lows because of full track being played on multitrack machines.
If you have two parallel plates forming a capacitor, the electric field does not end abruptly at the edge of the plates. There is some field outside that plates that curves from one to the other. This causes the real capacitance to be larger than what you'd calculate using the ideal formula. You have more electric field because of the fringe fields.
What were the advantages of the hierarchical system?
The hierarchical system has its advantages in that all those that live in a system understand what extortionists they need to pay and obey.
0.5 ppm is equal to how many microns?
According to:
http://en.wikipedia.org/wiki/Parts-per_notation
PPM (Parts per Million) is a unitless quantity, therefore it does not equal a distance.
As in water filtration, this would be equivalent to 0.5 parts of a particular dissolved solid to 1 million parts of water.
0.5 ppm Total dissolved solids are achieved in water using Reverse Osmosis plus a DeIonizing filtration, or through steam distillation.
What are the four essential functions of an automatic process control system?
1. to protect the plant
2. to support the plant
3. To respons to changes in the plant
4. to monitor process parameters
What is the purposes of log book in electrical sub-station?
A: The log book intent is to provide a history of events and people entry in case there is a later problem somehow the history can be analyzed to provide an answer quickly as opposed to searching for phantom problems
Solenoids are used in Car Starters, Rail road as electric switch. They are also used as valves to control the flow of fluid in appliance like washing machine.
How much clearance is need around 18000 volts to keep it from jumping to ground?
18000 volts clearance
How do you measure Phase difference?
The easiest way to measure phase difference is with an oscilloscope. Connect one channel to one signal, and connect the other channel to the other signal. Display both channels and trigger off of one. Measure the time difference - best accuracy is at the zero crossing point - and represent that as a percentage of the full period of one signal, normalized to 360 degrees.
If you are building circuitry to do this, there are many options but, basically, you are just repeating in circuitry what you do with the oscilloscope. There are some tricks... Assuming you are building a manual synchronizer for a generator, you can place a light bulb between the two phases, grid and generator. The light bulb will be at full brilliancy when the phases are 180 degrees out, and it will be dark when the phases are in sync. Still assuming the synchronization problem, you can connect the two phases to a special meter with two windings - the meter turns 360 degrees - and indicates phase angle - usually 12:00 is in sync - and most generators are designed to take the load when the generator is slightly faster than the grid and it is in the hot zone for being considered in sync.
Why is it called ansi 150 ansi 300 etc?
The number (e.g. 150) is the lb force the flange is rated to.
Why centrifugal pump is not called a positive displacement type of pump?
A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. Centrifugal pumps impart pressure to the fluid, to cause a pressure differential and cause flow, but even if the outlet is sealed, the pump can continue to run because it hasn't trapped the fluid. When no flow is occurring, a centrifugal pump acts like a propeller spinning in the water. If flow is stopped on a line that a positive displacement pump is supplying flow to, the pump is forced to stop since the trapped fluid prevents it from moving any more fluid.
