Oh yeah, and don't forget to impose a boundary condition on the stream function … WebThe stream function (see Section 2.5) at a point has been defined as the quantity of fluid moving across some convenient imaginary line in the flow pattern, and lines of constant stream function (amount of flow or flux) may be plotted to give a picture of the flow pattern (see Section 2.5 ).

WebThis is known as the operating line for the rectifying sectih iliihion, or the upper operating line, in short. Remembering that the x-y diagram is a plot of vapor (V) vs. liquid (L), it can be seen that the operating line is a simple y=mx+b equation. Therefore, with the point (xD,y1) and the slope (L/V), this operating line can be plotted.
