<p>Apparatus 300 and method 600 for determining non-extrapolated empirical data associated with the performance characteristics of a compressor 302 in the operating region where the head approaches zero or becomes negative. A test loop is created where an auxiliary compressor 314 is connected to a test compressor 302 in a loop, input to output of each compressor, and operated in the desired near zero to negative head region. While operating in this region, data is collected from sensors mounted adjacent to the process fluid input and process fluid output of the test compressor.</p> |
