A CFD model of steady two-dimensional incompressible flow has printed out the values of stream function w (x, y), in m2 /s, at each of the four corners of a small 0.4-m-by-0.4-m cell, as shown in the figure below. Use these numbers to estimate the resultant velocity in the center of the cell and its angle a with respect to the x axis. y = 1.9552 m²/s 2.0206 V ? a? 1.7308 m?/s 1.7978 The resultant velocity is The resultant angle is m/s.
