You must measure the viscosity of an oil that has an SG of 0.92. To do this, you put the oil into a large container to the bottom of which a small vertical tube, 25 cm long, has been attached, through which the oil can drain by gravity. When the level of the oil in the container is 6 in. above the container bottom, you find that the flow rate through the tube is 50 cm3 /min. You run the same experiment with water instead of oil and find that under the same conditions the water drains out at a rate of 156 cm3 /min. If the loss coefficient for the energy dissipated in the contraction from the container to the tube is 0.5, what is the viscosity of the oil?
