water flows smoothly from the left-hand pipe section (radius 2.00R), through the middle section (radius R), and into the right-hand section (radius 3.00R). The speed of the water in the middle section is 0.460 m/s. What is the net work done on 0.430 m3 of the water as it moves from the left-hand section to the right-hand section?
