Basic Thermodynamics Of Reciprocating Compression
MetadataShow full item record
This tutorial provides a straightforward explanation of how a reciprocating compressor works relying heavily upon the pressure- volume diagram (P-V diagram) as a point of reference. The discussion begins with a thorough review of the P-V diagram. Next, how capacity is determined and calculated is discussed, which requires an explanation of volumetric efficiency. How much power is required to compress a certain volume of gas is then explained involving detailed discussions of adiabatic, valve loss and friction power. The tutorial will then delve into discussions of compression efficiency and how changes in pressure and rotating speed affect the P-V diagram. The tutorial should be an excellent introduction for the inexperienced and a solid refresher for the experienced.
