Figure 7-8 depicts a streamline for two-dimensional flow and its associated equipotential lines 1 to 10, each normal to the streamline. The spacing between the equipotential lines is given in the second column of the table on page 115. If the average velocity between 1 and 2 is 0.500 ft/sec, calculate (a) the average velocities of the streamline between each pair of equipotential lines and (b) the time it will take for a particle to move from 1 to 10 along the streamline.
