(10 points) A 50-mm -diameter plastic tube is used to siphon water from the large tank shown in the figure below. If the pressure on the outside of the tube is more than 35 kPa greater than the pressure within the tube, the tube will collapse and siphon will stop. Assume that viscous effects are negligible. (a) At what flow velocity (in m/s) will the tube collapse? (b) Determine the minimum value of h (in m) allowed without the siphon stopping. (2) 2 m (1) (3) 4 m h
