In the method of Helmholtz-Kirchhoff for separated flow past a flat plate (normal to the stream) the separation velocity and the "base pressure"are fixed at the free-stream values. In the present treatment a modification is introduced to allow arbitrary separation velocity and base pressure, so that values more in conformity with experiment may be chosen. The solution depends then on the single (base-pressure) parameter k. When k is suitably chosen, the drag and the details of the potential flow near the plate agree well with experiment. The computations, depend on a particular choice of free-streamline hodograph, which has the feature that it gives a definite wake width for every value of k. In this way the wake is correlated with the drag.
