    This paper describes the behavior of steady and unsteady flow inside a centrifugal compressor stage. Time averaged and unsteady pressure measurements were carried out using high response pressure sensors to capture the flow behavior within the impeller channel. Experiments were carried out at five different speeds. At each speed the different operating points were .obtained through a throttle control valve. From the measurements the critical regions in the stage which influence the performance has been identified. It was observed that the flow entering into the diffuser is non uniform and becomes uniform as the flow leaves the diffuser. At low flow rates there is a rise in static pressure at impeller inlet tip
