Yes a two stage Piston Compressor will be much economical than a single stage screw compressor.
They are the same thing.
Reciprocating compressors are positive displacement in machines. However, separable compressors have higher maintenance costs.
Piston Centrifugal Vane Roots
A single-stage compressor is a type of compressor that compresses gas or air in a single step, raising its pressure from inlet to outlet in one operation. It is more commonly used in applications where a moderate increase in pressure is required, such as in residential air conditioning units or small workshop tools.
Most are cycling clutch piston compressors, with the wobble plate method of cycling the pistons probably being the most common. Rotary and vane compressors can also be found, the latter being almost predominant in hybrid vehicles.
compressors,gear pumps and all the pneumatic tools use this law
This is a type of high tech ultra light weight aluminum piston material for use in automotive engines. It has desirable strength and weight characteristics in comparison to cast pistons but lacks strength in comparison to Forged materials in piston manufacture.
The piston rings create a seal between the piston and the cylinder wall.
The answer is Compression Ratio. You should try reading the Study Unit it really helps!
diameter
A type of reciprocating/positive displacement compressor in which the gas is compressed using a piston cylinder that is connected to a crankshaft. As a result of the flywheel rotation, the crankshaft moves the piston causing it to compress the air. The most common application for such type of compressors are the internal combustion engines
No fit.BECAUSE No contact between piston and cylinder.
