A CFD model of steady two-dimensional incompressible flow has printed out the values of stream function \( \psi(x, y) \), in \( \mathrm{m}^{2} / \mathrm{s} \), at each of the four corners of a small \( 2.7-\mathrm{m} \)-by-2.7-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 \( \alpha \) with respect to the \( x \) axis.
