【Help】Power issue with reciprocating compressors
Thread Content
Dear experts, I have a question. In many books, the formula for calculating the power of a reciprocating compressor is given as follows: Power N = 16.745 * p1 * qv * k / (k – 1) * (z1 + z2) / (2z2) * 1/η, where p1 is the inlet pressure, qv is the volume of gas discharged under the inlet conditions, k is the specific heat ratio of the gas (Cp/Cv), z1 and z2 are the compression coefficients of the gas under the inlet and discharge conditions respectively, and η represents the efficiency. 16.745 seems to be a correction factor that is related to the model of the compressor as well as its operating conditions. Does anyone know how this correction factor should be determined correctly?
The entire correction factor should be provided by the compressor manufacturer! I really haven’t calculated it
The constant calculated during unit conversion
Could you explain it in detail? How was it calculated?
