What are the examples of instrumental error?
If an instrument is indicating a wrong parameter instead of actual. Say the actual pressure is 1 bar but the instrument is reading 1.5 bar is an example of instrumental error.
What means of 2Hi rolling mill?
"HI" is a latin word, its real meaning is horiontal roll, now u can easly understand the meaning of 2hi, 4hi, 6hi & 20 hi , for example 2hi mean two horizontal roll which is used for rolling the iron.
Why need to study industrial engineering?
Industrial Engineering is a extended branch of Mechanical engineering but now stands a separate entity. It involves work study, method study, time study, optimization techniques, value engineering. It focuses on improving the way a work or job is done. If one wants to improve an activity, optimize an activity either by man or machine, Industrial Engineering tools offer solution.
How much an PLC have outputs and inputs maximum?
There are PLC with fixed inputs and outputs. There are modular ones which can be added on with inputs and outputs. So number of input and output of a PLC is actually based on the type of PLC you choose. Different types are available in the market.
What is the meaning of allocation meter?
Allocation is the process of assigning the proper portions of aggregated product flows back to
individual source streams, owners, leases or measurement point. The assignment process is a
standard method that is agreed upon and used by contracting parties. It is designed and intended
to be fair, cost efficient and practical. By providing an efficient product sales transaction
mechanism, allocation measurement helps to reduce capital and operating costs without
jeopardizing the principal goal of fair treatment among parties. Reducing fluid measurement
costs facilitates the development of marginal fields.
Allocation measurement can fall under federal or regulatory guidelines. Individual agreements
must meet or exceed those guidelines. API MPMS Chapter 20.1 is the industry's allocation
measurement standard. Without it volumes of technical measurement documents would be
required to accompany commercial contracts. The first edition of API 20.1 was prepared in 1993
and recently reaffirmed in 2006. Its scope is to provide a set of design and operating guidelines
for implementing liquid and gas allocation measurement systems. As such, it provides
recommendations for metering, static measurement, sampling, proving, calibrating, and
calculation procedures. Due to the breadth of the measurement topics covered under allocation
measurement, API Chapter 20.1 focuses on identifying procedures, providing practical and
technical guidance in implementing allocation metering systems, and acts, in part, as a master
guide to other important measurement guidelines.
Individual allocation meters determine the portion of flow that is attributable to an individual
source stream. The allocation meters may or may not meet custody transfer standards, although
the total production should be determined with custody transfer quality systems and procedures.
For example, it may be necessary to use multiphase metering with a higher degree of uncertainty
at some sites in order to reduce the requirement for separation equipment. Commingling of fluids
with differing qualities and properties leads to the need for periodic testing and validation in
order to better define the quality and quantity of the streams. Design, measurement equipment,
and practice choices must be made but they must be applied in a fair and uniform manner
throughout the system. Ultimately, the quality and quantity determinations in an allocation
system must represent the contributions from each individual source stream - lease contribution.
Existing custody transfer standards form much of the basis for the measurement methods used in
allocation. If Chapter 20.1 does not specifically address a measurement issue, then it should be
assumed that the appropriate custody transfer standards apply for that issue.
Is titanium stronger than platinum?
Yes.
In fact, titanium was the strongest material on earth until just recently.
Where do you use reciprocating pumps in daily life or in industrial applications?
Daily life you use reciprocating pumps buy using your water faucet, pumping gas or simply using a suringe for medicine.
What is the importance of string diagram in industrial engineering?
it is useful for analysing the movements in short cycle repetitive jobs.
What is isolator with earth switch?
A disconnector or isolator switch is used to make sure that an electrical circuit can be completely de-energised for service or maintenance. Such switches are often found in electrical distribution and industrial applications where machinery must have its source of driving power removed for adjustment or repair. High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers and transformers, and transmission lines, for maintenance. Often the isolation switch is not intended for normal control of the circuit and is used only for isolation; in such a case, it functions as a second, usually physically distant master switch (wired in series with the primary one) that can independently disable the circuit even if the master switch used in everyday operation is turned on.
Isolator switches have provisions for a padlock so that inadvertent operation is not possible (see: Lockout-Tagout). In high voltage or complex systems, these padlocks may be part of a trapped-key interlock system to ensure proper sequence of operation. In some designs the isolator switch has the additional ability to earth the isolated circuit thereby providing additional safety. Such an arrangement would apply to circuits which inter-connect power distribution systems where both end of the circuit need to be isolated.
The major difference between an isolator and a circuit breaker is that an isolator is an off-load device intended to be opened only after current has been interrupted by some other control device. Safety regulations of the utility must prevent any attempt to open the disconnector while it supplies a circuit.
Standards in some countries for safety may require either local motor isolators or lockable overloads (which can be padlocked).
What size of generator to run 5.5kw 400v 50Hz motor?
You need a 5.5kw generator to run a 5.5kw motor.
What filler metal do you use to weld 1018?
According 00-25-252 W.O 007-001 Pg. 4 states that 5632 is the best filler for welding 1018.....
How is metric thread pitch measured?
Metric thread pitch is measured directly from crest to crest of the thread form.
For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM.
Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.
What is the purpose of hidden lines?
so you can see objects that are behind the object you are looking at
What is recrystalline temperature?
Recrystallisation temperature is the temperature at which the crystal structure starts forming.
What is Difference between peak inverse voltage and break down voltage?
Two names for practically the same condition. Peak inverse is name whereby the maximum voltage can be sustained. Breakdown is actually the point where a reverse voltage is reached and reverse breakdown has occurred
Why is titanium more useful than steel?
That depends on what you want it for. Ti can be as strong as steel, but a lot lighter, which can be useful.
However, Ti is a lot more expensive, so unless weight is really important, you might prefer steel anyhow.
Steel can also be made more wear resistant, and is easier to make good cutting tools of, which is important in some cases.
Aerodynamic shapes are those that tend to minimize or eliminate the production of turbulence in a liquid medium (including air and gasses) as the medium and the shape move relative to one another. It makes no difference if the shape is moving through the medium, or the medium is moving around the shape. The point is the same: lower turbulence. Aerodynamic shapes typically have tapered leading edges that present to the stream. Then they typically widen to their maximum width and continue to taper to their trailing edge. The waterline of a kayak or canoe are good example of a typical aerodynamic shape.

Two hazards using a pillar drill?
A pillar drill is another name for a drill press. The biggest hazards are objects getting wrapped around the chuck, and debris or projectiles being thrown. So long hair, ties, and loose clothing should be avoided, eye protection should be worn, and your work should be securely clamped to the work area.
Other hazards could include drilling oneself, being injured inside the gearbox, or starting a fire. So you should keep all body parts from around the chuck and pulleys while the drill is in operation. You should be careful to not let your work get overly hot, not operate the press in the presence of flammable vapors, and not overload the outlets.
