ABSTRACT:
The invention relates to a method and device for obtaining a determined flow resistance of a flow channel, especially an opening in a component. The method involves the following steps: a liquid flows through the flow channel; a characteristic depending on the flow resistance of the flow channel in the component is determined; and the flow channel is machined by means of a working method until said characteristic reaches a pre-determined nominal value.
