Compressor surge only occur in centrifugal compressors. reciprocating compressor don't as they increase pressure by volume reduction, unlike centrifugal compressors where they increase pressure by converting kinetic energy to potential energy (pressure).

When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.

In Volute Casing, area of flow increases gradually, Due to this, the amount of movement of water opposite to the general flow of water is more. This movement of water against the actual flow of water is called EDDIES in Volutes casing of Centrifugal pump.Where as in Vortex casing area of flow is uniform and effect of formation of eddies is very less.

The backplate is simple turning with only some aspects of work holding posing any problems.

a stress strain curve and a load displacement curve is pretty much the same thing, given the data is from the same specimen.

its just the stress (force/area) is divided by a constant area and the strain (change in length/original length) is divided by a constant original length.

therefore your curve would pretty much look the same as dividing by a constant will not change your graph.

Tensile strength is determined from testing a large number of samples. Some will fail higher or lower than others, and an average strength is determined. Minimum tensile strength is usually calculated from statistics using a Weibull probability analysis. In this case the minimum tensile strength usually is reported as the Weibull A value, which is the value at which 99% will survive with 95% confidence. Weibull B, usually based on fewer samples, is the minimum value determined to survive with 90% reliability and 95 % confidence.

At the time of turning long bars the follow rest and steady rest are used.

Follow rest is used near to the tool at the back side of the job ie bar and it moves along with the tool such that it gives support to the job so that the job does not get deflected due to the tool preacher.

Steady rest is used to give support to the job in the middle or at a end so that the job should not get bend.

Due to the difference in kiln shell outer and tyre inner diameter,kiln revalotion is more then tyre.The slippage of shell inside tyre is called migration.When tyre and kiln become rigid so the air gap become zero between both and migration get zero.Migration tell us only that there is air gap.actual air gap is necessery for shell expantion.

Pressure increases due to load(or heat intake from evaps).if asking about off cycle. If asking about compression cycle,its the compression of vapor into a higher pressure side of system along with heat of compression adding to temp-pressure relationship.

The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..

A: Because it is a very good conductor has many electrons 27 if I can remember correctly. There is a draw back to using silver that is because has the tendency to oxidize with oxygen as tarnish which occasionally must be eliminated to provide a good connection

not quite sure the exact but compressor is used to compress a fuel while engine changes the fuel into useful mechanical energy.

It may gall if it is of the same material as the bolt. It may need to be lubricated, that will prevent this; also, if over-torqued it may gall or strip the thread.
