8. Suppose we narrowed the diameter of the tube such that the left half of the tube's diameter is unchanged, and the right-half of the tube's diameter is now smaller. Using the continuity equation (1 1 1 = 2 2 2), describe how the fluid velocity changes as it passes through the tube. Show all your work for any credit.

9. About halfway down the tube click to grab the handles (shown above) and narrow the diameter of the tube. In the space below, copy and paste a screen shot of your adjustments. Using the speedometer to the measure the fluid's velocity, perform theUsing the speedometer to the measure the fluid's velocity, perform the simulation and describe how the velocity of fluid varies across the length of the tube. Do the predictions from question 8. agree with the results here?
