Figure 1.
The schematic contains a vertical axis of symmetry with g directed downward beside it. A slanted wedge surface extends upward from the origin. The wedge surface has x, u marked along it. A slanted line on the opposite side marks T sub w. An angle near the origin is labelled pi beta between the symmetry axis and the wedge surface. A downward slanted direction from the origin is labelled y, v. T sub infinity is marked below with an upward arrow. B sub 0 is marked near an arrow pointing toward two dashed curved lines beside the wedge surface. The equation states u sub e equals u sub infinity x bar raised to m.Schematic diagram and flow geometry
