This question requires a very expansive list of items, which would take hours to compile.

Unfortunately we haven't time available to dedicate that long to a single question.

Without wasting your time you might just let someone list an overview of the main parts of a car engine which are necessary for its function and maintenance..................

HRC 23-34 According to ASTM F568M (1996)

Decentralisation promote accountabilty in policy implemention because the people get involved and are aware of the policy taking place.

Ferrite number is a measure of = Chromium & Nickel equivalent in an Austenitic stainless steel material. It should be between 3-7% max. Very low ferrite can lead to cracks. It is a measure of denoting the ferrite content in an stainless steel. Ferrite Number has been adopted as a relative measure for quantifying ferritic content using standardized magnetic techniques. The Ferrite Number approach was developed in order to reduce the large variation in ferrite levels determined on a given specimen when measured using different techniques in different labratories.

The ferrite level is only important to assure minimum exposure to solidification cracking when depositing austenitic stainless steel weld metal. The lower ferrite number is better for corrosion resistance, while balancing higher ferrite content to avoid solidification cracking in the weld deposit. I would not worry about lower ferrite numbers for clad overlay welding, if no cracking is observed (Liquid Penetrant verification).

A manhole invert is the pipeline running across the bottom of the manhole, from the point where the incoming pipe enters until the outgoing pipe discharges the outflow. It is frequently expressed as an elevation level where this pipeline sits.

Okay, to get the static pressure in your duct to from 0.5" water gauge (w.g.) to 1.5"w.g., you could add another fan in series. Or, depending on your existing fan and motor size, you may be able to speed up your current fan to the pressure value desired. Additional airflow would be dampered down.

Fluid flow in an annular space occurs during a drilling operation of the gas and oil well. The correct prediction of the flow lies in the drilling mud in the annular space between the well.

A brine solution is silmply water that is combined with diluted salt. It allows the water that is used in chilled water cooling systems to operate a lower tempertures without freezing up. Just like freon (refrigerant) used for residential cooling systems, the chilled water flows through an evaporator coil in which heat is absorbed and to be carried away by the mixture which cools the ambient space. On other applications, an antifreeze, or glycol solution, in the chilled water performs a similar task.

An axial load is a force administered along the lines of an axis.

This is typically used to describe an injury in which there is compression of the spine from the head, such as when a person dives head first into shallow water and hits the top of his head on the bottom. This frequently causes fractures of the spine and possibly spinal cord injury.

It is also commonly used to describe a specific strength of materials known as their uniaxial compressive or tensile strength and also to find the variation of their strength with increasing confining pressure (as used in triaxial testing).

No! It will not work as a purifier works using central fugalforce (spins dirty fuel to the outside). Lubricating oil is heavier so it cant be used. On marine purifiers any dirty fuel is dumped into a sludge tank after the sensor realises there is more than 15 parts per million. If you were to use lubricating oil the sensor will dump all of it as it is too thick.

f2413-05 has something to do with chain saw protection. and I think 175/c75 is some kind of osha requirement for safety footwear?

F2413 is the ASTM designation for footwear protection standards for work boots. The "-05" signifies the 2005 version which was updated in 2011 and is signified with "-11" suffix. The last part "I75" (not 175) and "C75" designate (I)mpact resistance of 75 ft lbs and (C)ompression resistance of 75 ft lbs (there are boots that only resist 50 ft lbs also that would bear the designation I50 C50). There are further designations for various other properties. . .EH = Electrical isolation to help prevent electrocution. .CD - Conductive (i.e., it allows electrical grounding) for use in potentially explosive environments (where gases, explosives and volatile chemicals are present). .SD = Static Dissipative (kind of a combination of EH & CD). .PR = Puncture Resistant. .CS - Chain Saw resistant. .DI = Dielectric (a higher grade EH, I believe).

Most centrifugal chillers require a constant water flow, therefore a VFD would not be of any use.

True

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.

A JLG is a brand name of mobile personal and equipment lifts used extensively in rigging.

For good pay scale, after completing mechanical engineering the courses are CSWIP CERTIFICATION COURSE, DESIGNING, CAD/CAM, or else plan for MS if it is affordable.
