Dear friends;
I am going to report the power for a compressor which shall transmit natural gas through pipeline.In this regard I have some questions .
First of all I want you to refer me to a good reference or guideline to calculate the power required for different type of compressors.I have found several methods but I am a little confused especially regarding the efficiency which shall be used in calculation(e.g. isentropic, polytropic,...).how can I calculate efficiency?
The other concern is about the difference of figures for duty that are calculated based on formula and output of some simulation software like hysys.would you please somebody make it clear for me?
thanks in advanced

sah,

Check out the following links for an answer to your query:

Additionally you may wish to preview a spreadsheet for centrifugal compressor head and power calculations available at "Cheresources" online software store for a nominal price. This spreadsheet gives results in close tolerance to calculations done through HYSYS simulation software. A lot of equations are given for the sake of easy understanding and simplicity:
