The figure above shows a horizontal tube with a constriction and two open, vertical columns. The inner radius of the larger section of the horizontal tube is 1.45 cm. Water passes through the tube at a rate of 0.18 L/s. If h = 10 cm and h = 8 cm, what is the inner radius at the constriction? Ignore the viscosity of water. (Note: This is the most difficult problem assigned in the course. This is only for the most ambitious students. To solve this you will need to use various concepts of continuity, Bernoulli's law, and hydrostatic pressure. Check that your answer makes conceptual sense.) Rconstriction = cm
