Diagram of a rotary screw compressor In an oil-flooded rotary screw compressor, oil is injected into the compression cavities to aid sealing and provide cooling sink for the gas charge. The oil is separated from the discharge stream, then cooled, filtered and recycled. It is usual for some entrained compressor oil to carry over into the compressed gas stream. In some applications, this is rectified by coalescer/ filter vessels. Standard oil-flooded compressors are capable of achieving output pressures over 200 psig, and output volumes of over 1500 cubic feet per minute (measured at 60 °C and atmospheric pressure). In an oil-free compressor, the air is compressed entirely through the action of the screws, without the assistance of an oil seal. They usually have lower maximum discharge pressure capability as a result. However, multi-stage oil-free compressors, where the air is compressed by several sets of screws, can achieve pressures of over 150 psig, and output volume of over 2000 cubic feet per minute (measured at 60 °C and atmospheric pressure). Oil-free compressors are used in applications where entrained oil carry-over is not acceptable, such as medicial research and semiconductor manufacturing.
The same as the purpose of any physical theory: to explain how our world works.
One can find pictures on how the human hearts works primarily online, for example, The British Heart Foundation website, and other sources such as How The Heart Works and Pictures of the Heart.

A diagram.
In the reciprocating compressors, you fill the crank case with the lubricante. In screw compressors, there is a reservoir to separate oil from compressed air, that reservoir works as the oil sump of the screw compressor. in big centrifugal compressor oil is placed in an oil tank, and than is pumped to bearing casings by means of mechanical or electrical pump.
In computing - a flow diagram helps the programmer to see that each instruction and branch works correctly.

A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
a screw works better cues it has threads and a nail is just goes straight in the board. The nail is stronger but the screw holds tighter.
You insert the point into an appropriate screw and rotate the handle clockwise to screw in and the opposite to screw out.
