Water flows steadily through a pipe of 20cm diameter, which subsequently converges to a pipe of diameter of 5cm. The velocity profile upstream in the 20cm section is varible, symmetric with radius r and given by V=180-r^2 in cm/sec with r in cm. Determine the mass average velocity in the 5cm section.
