How did they find assembly line balancing?
1) First you need to construct a precedence chart of tasks. For example:
A ----> B ----> C ----> D
2) Next, do time study to determine how much time required to perform each task.
A (4 mins) ----> B (2 mins) ----> C (2 mins) ----> D (2 mins)
3) Find the takt time. Takt time = available production time per day/customer demand per day
4) Calculate the minimum number of workstations required, given the task times above. Below is the formula:
Min # workstations = Total time for tasks divided by takt time
Hope it helps!
Distance between 2 rugs of ladder?
The distance between steps shall not exceed 12 inches, thus two rungs equal 24 inches
Can one step up power from inverter with step-up transformer?
No. You can not step up power with a transformer. You can step up voltage, while stepping down current, or you can step up current, while stepping down voltage, but you cannot step up (or down) power.
What is the Optical Time Domain Reflectometer OTDR used for?
An OTDR may be used for estimating the fiber's length and overall attenuation, including splice and mated-connected losses. It may also be used to locate faults such as breaks.
How to calculate head presure of a water tank?
Just measure the elevation of the max water height above the ground (or whatever reference level you wish to use).
What is the weight of 1squared meter of paper honeycomb?
It depends on the thickness of the core paper and cell size.
How do you save the used transformer oil resource for reuse?
Transformers oil conditioners, purification and reclamation addresses the higher cost for oils and ever increasing environmental regulation and liability. It is no longer economical to replace electrical insulating oils to renew their dielectric strength. Restoring these oils to their original strength through purification is now a necessity. High Vacuum transformer oil purification systems are designed specifically to meet the operational, economic and environmental needs of industry in purifying insulating oils. Through proven dehydration, degasification, and filtration techniques, the hi-vac oil purification systems quickly and easily remove:
ZY series high effective vacuum transformer oil purifier is just such a type machine, which is designed for recycling used or dirty new oil unused for long time.
This machine is special for purifying various of insulating oils including transformer oil, mutual inductor oil and switch oil etc. It is widely applied to the areas of power station, transformer substation, railway, petroleum, chemical and metallurgy. Also it is the best choice for filling oil into power equipment and drying moisture of power equipment. It can quickly and effectively removing the impurities, gas and water, which can benefit to improve the withstand voltage of oil and prolong the lifetime of oil.
It is mainly applied for oil purification in fields of electrical apparatus manufacture factory, power station etc...
The machine, which is suit to electrical apparatus manufacture factory, power station, power supply department, transformer in railroad station and other department.
It can can filter insulation oil for transformer, mutual inductor, electricity capacitance and hi-pressure switch.
For special applying, it also can deal with vacuum filtering and dry the heating oil circulation for the large electrical apparatus.
Distinctive removing the impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power.
Bi-infrared liquid Duplex 3D stereo-evaporation technology, dewatering and degassing very effectively.

What is the leakage class of control valve?
The Leakage Class of a Control Valve can be: Class I: any rate agreed to by the buyer and seller. Class II through Class IV: range from being a .5% to .01% of full flow Class V and Class VI: These two ranges are fairly tight shut off classifications and are rate in bubbles per minute under test conditions set forth by the NIST. More information about the test conditions and measurement details can be found online.
Why are interchangeable parts important?
There important because they can sped up the production process, make repairs easy, and allowed the the use of lower paid an less skiled workers.
Is a amythyst stronger than gold?
It's hard to compare the two since an amethyst is a gemstone and gold is a metal, but gold is a relatively soft metal and amethyst is a relatively hard gemstone, so an amethyst would be considered stronger than gold.
Gold follows all characteristics of mineral
First: Its inorganic
Second: It occurs naturally
Third: Its a solid crystallized form
Fourth: It has consistent chemical composition
Fifth: It forms crystals
In a boiler, pitting is dangerous because it weakens the boiler plate by reducing its thickness and strength. A pit that reduces the boiler plate thickness (at its weakest point) to 1/4 of the original thickness will fail at its Maximum Allowable Working Pressure. The weakest point is typically at the longitudinal joint (welded or riveted boilers) and pitting, grooving and cracking at this joint is closely monitored in all boilers.
What is the proportional integral and derivative control system response?
The proportional integral and derivative control system or PID control system consists of proportionsl, derivative and integral elements which gives a very efficient process control.
answ2. Cones. Assuming you mean the optical colour sensors, these come in three colour sensitivities, (just known as Short, Medium, and Long) and these give us colour vision. You have about 5 million cone cells in each eye, and about 90 million rod cells.
The rod cells see only light, not colour, but are about 100 times more sensitive than the cones. This is why at night, you have inferior colour vision.
Your cone cells are grouped in the centre of your vision, the fovea, and you'll easily be able to see things at night, "out of the side of your eye" by looking slightly away from your subject of interest. In fact, you may even see a 'hazy region' in the middle of the field of view where there appears to be no definition. This is because the (inactive) cone cells dominate in this region.
Most animals have no colour vision, for it is of no advantage to them. Birds, bees and butterflies have excellent colour vision (Up to five colour sensors) for their ability to distinguish fruit ripeness is vital to them.
How do you identify EPDM rubber?
The best way is via infrared analysis. If you do not have any instrumentation available, you can burn a small piece of the rubber. When removed from the flame EPDM will give off a sooty smoke that smells waxy (like a burning candle).
What metric class of fit is f7?
f7 (yes, it really does matter whether you use an upper case or lower case letter) is a shaft tolerance, which is, generallyspeaking, used for close tolerance (clearance) fits.
But it depends on the size of the mating component.
What is a difference between b-15 lens on ray-ban glasses and polarized lens?
B-15 lens are brown in color and G-15 lenses are gray-green. Polarized lenses come in both colors and on the lens it's written Ray Ban P
How is rapid prototyping in China?
China's rapid prototyping industry has been developing very rapidly during last 2 decades. Some good rapid prototype makers emerged from themarket and gradually is gaining world reputation.Uidea Rapid Prototype China Co., Ltd. is one of leading players.
Originally, the Hongkong people andTaiwanness set upprototyping companies in China mainland, mainly inpearl river delta area, in the cities like Shenzhen, Dongguan and Guangzhou.Sincethe beginning of thiscentury, many local Chinese who usedtowork in HK or Taiwan rapid prototypingcompaniesstarted to found their own business.
Compared with rapid prototyping service in other countries, rapid prototyping in China still has significantly cost advantage, expecially the CNC machinied prototypes, vacuum casted protoypes, reaction injection molding,rapidtooling, rapid injection molding and extrusion prototyping. Uidea Rapid Prototype is one of the largest professionalintegrated rapid prototyping companies in China.
