How to calculate the standard-condition discharge volume of a reciprocating compressor
Thread Content
Dear group members: How is the standard-condition discharge volume of a reciprocating compressor calculated? The gas being transported is natural gas; the inlet pressure is 2.7 MPa (gauge pressure), and the outlet pressure is 5.5 MPa (gauge pressure). The compression capacity of the compressor is 14.77 m3 per minute. Thank you!
As a rough estimate, it can be calculated using the ideal gas law; you also need to know the intake air temperature. The formula is pv=RT – use this to do the calculation yourself
Standard conditions refer to a certain pressure; you just need to make the conversion.
5.5 MPa (gauge pressure), 14.77 m3/minute – this flow rate refers to the volume at 5.5 MPa; converting it to a pressure of 0.1 MPa gives the flow rate under standard conditions.
