Question:

To determine the viscosity of a liquid of specific gravity 0.95, you fill, to a depth of 12 cm, a large container which drains through a 30-cm-long vertical tube attached to the bottom. The tube diameter is 2 mm, and the rate of draining is found to be 1.9cm3/s. What is your estimate of the fluid viscosity? Is the tube flow laminar? Fig P6.18
