Two one liter beakers, 12 cm in diameter are connected via their bottoms by 10 cm of Tygon tubing 1 mm in diameter. The bottoms of the beakers are at the same level. The one on the left is filled with 1 L of water at 20 C with a coefficient of viscosity of 1 cP. How long will it take for the beaker on the left to have 60% of its original level.
