Question:

Figure P8.71 shows the streamlines and potential lines of flow over a thin-plate weir as computed by the complex potential method. Compare qualitatively with Fig. 10.16a. State the proper boundary conditions at all boundaries. The velocity potential has equally spaced values. Why do the flow-net €œsquares€ become smaller in the overflow jet?
