A typical capillary viscometer has a large-diameter reservoir and a long, small diameter, vertical tube. The sample is placed in the reservoir and the flow rate due to gravity is measured. The tube is 0.1 m long and has a 1 mm ID. The height of the fluid in the reservoir above the inlet to the tube is 0.02 m. The fluid being tested has a density of 1050 kg / m'. The flow rate is 10* m' / s. What is the viscosity of the fluid?
