Most small airplanes are not air tight (or even completely encased) because thy do not need pressurization. Commercial planes fly at altitudes where there is not enough oxygen to sustain life, requiring pressurization.

Agar probes are use in applications where there is an oil/water interface that needs to be monitored. Often in such interfaces an emulsion occurs (a mixture of oil and water droplets). Such emulsions make it difficult to determine between the emulsion and the pure water/ pure oil strata, using standard methods such as a float level. Agar probes emit microwaves, which are readily absorbed by water but not by oil. By measuring the level of microwave energy absorbed by the surrounding fluid the agar probe can be use to determine whether it is in a water, oil or emulsion strata. A typical application would be in the oil and gas production. The purpose here is to separate and remove pure water used in processing from waste oil. Since this water can be recycled for reuse in processing or even pumped back into the environment, it is important that only pure water and not oil or an oil/water emulsion is pumped from the seperator tanks. Agar probes are a reliable way of ensuring this.

One change in agriculture that occurred in the 1800's as a result of advancements in science and technology is large scale watering. Other are new crop varieties and inventions of farm machines.

applications of quenched steel plates

these are used to make dies for extrusion ,nozzles armour plates

temperd steel bars

they are used for deep drawing to form shapes and also to ships hulls , these are used where strength ductility are important

A blind elevator shaft has a hoist-way door meaning that it won't stop on every floor like most elevators do. Most of these installations are used in buildings where celebrities or 'important' types of people want very little interaction with others or the general public.

What is the difference between HRC and CRC steel sheet?

Cold rolling is a metallurgical process in which metal is passed through a pair of rollers at a temperature below its recrystallization temperature. This process hardens the metal, by compressing and stretching the metal crystals. During the rolling process, the metal is annealed by heating it above the recrystallization temperature after every few rollings, to prevent it from becoming brittle and cracking.

Cold rolled metal is given a "temper" rating based on the degree it was compressed. "Skin-rolled" metal undergoes the least rolling, being compresssed only 0.5-1% to harden the surface of the metal and make it more easily workable for later processes. Higher ratings are "quarter hard," "half hard" and "full hard"; in the last of these, the metal is compressed by 50%. Metal hardened by cold rolling can bend without breaking, although ductility decreases as the hardness increases. Quarter hard metal can be bent entirely back on itself, while full hard can only be bent 45°.

Most non-ferrous metals are rolled cold to make sheet. Steel is usually rolled hot, except when thin sheet or special bars such as machine shafts are being produce

The metallurgical process of Hot rolling, used mainly to produce sheet metal or simple cross sections from billets describes the method of when industrial metal is passed or deformed between a set of work rolls and the temperature of the metal is generally above its recrystallization temperature, as opposed to cold rolling, which takes place below this temperature. This permits large deformations of the metal to be achieved with a low number of rolling cycles.

Because the metal is worked before crystal structures have formed, this process does not itself affect its microstructural properties. Hot rolling is primarily concerned with manipulating material shape and geometry rather than mechanical properties. This is achieved by heating a component or material to its upper critical temperature and then applying controlled load which forms the material to a desired specification or size.

Mechanical properties of the material in its final as-rolled form is a function of: the material chemistry, reheat temperature, rate of temperature decrease during deformation, rate of deformation, heat of deformation, total reduction, recovery time, recrystallisation time, and subsequent rate of cooling after deformation

Easy to manipulate.

Compact storage.

(those are also the disadvantages)

Cyber-Rig is a physical model of a semi-submersible drilling unit. The model has eight rotatable azimuth thrusters, two on each leg. The task in control allocation is to generate the generalized forces (surge, sway, yaw, pitch and roll) the controller specifies with the available control effectors/actuators. As a specified force vector can be generated in several different ways, the secondary objective in control allocation is to minimize some criteria, for instance energy consumption.

Foundry is a technology of casting metals into shapes by melting them into a liquid, pouring the metal in a mold, and removing the mold material or casting after the metal has solidified as it cools.

Technically, A thermoset cannot be reused since it forms a structure that does not remelt easily and remelting this material can result in degradation and molecular weight changes. A thermoplastic however can be reused when mixed with a percentage of virgin material. This is the large benefit of utilizing a thermoplastic over a thermoset.

both are same using for rotating the turbine initially

yes modern steam engines

Over 24" the spec changes to B16.47. For a complete listing of dimensions on the flange side of B16.5 and B16.47 check out www.texasflange.com

earth fault relay is similar like earth leakage ralay,but the 2nd one is more sensitiv.

E furnace (made ferro manganese) and L furnace were shut down the night of July 20, 1977 due to the Johnstown Flood that caused the plant to lose power and water damage which caused the blowing turbines to shut down.

H furnace was saved due to it being relined in 1976 and was idle when when the flood struck. H was restarted and operated until Aug 1981 when it was abandoned when Johnstown was changed to electric steelmaking furnaces.

H furnace was never fully tapped out. It was torn down and the iron that was left in the hearth is still visible. It was said that iron recovery was attempted, but it

was unsuccessful so it was left as a sort of monument.

What was the Franklin division has been demolished except for the building that housed the plate mill which appears to slated for removal. 3/10/12
