1. A turbomachine, wherein the turbomachine defines a flowpath therethrough at which a fluid is compressed, the turbomachine comprising:
a first compressor in serial flow arrangement upstream of a second compressor;
wherein the second compressor comprises a port at the flowpath, wherein the port at the second compressor is configured to receive at least a portion of the fluid from the flowpath from the second compressor;
wherein the first compressor comprises a vane positioned at the flowpath, and wherein the vane comprises an opening at the flowpath, wherein the opening at the vane is configured to egress the portion of the fluid from the port into the flowpath:
at least one controller configured to execute operations, the operations comprising;
rotating the first compressor and the second compressor to generate a compressed fluid therethrough;
removing, via the port, at least a portion of the fluid from the flowpath at the second compressor; and
adjusting an operation line at the first compressor based at least on egressing at least a portion of the portion of fluid from the second compressor through the vane at the first compressor.
