Example 6.2. Figure 6.7 shows a simplified flow diagram of a typical capillary viscometer (a device for measuring viscosity). It 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 3 m. The fluid being tested has a density of 1050 kg / m The flow rate is 10-8 m³/s. What is the viscosity of the fluid?

Example 6.2. Figure 6.7 shows a simplified flow diagram of a typical capillary viscometer (a device for measuring viscosity). It 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 / m³ The flow rate is 10-8 m³/s. What is the viscosity of the fluid? FIGURE 6.7 Typical capillary viscometer; see Example 6.2.

6.6. In Example 6.2 how much does the internal energy per unit mass of the fluid increase as it passes through the viscometer? Assume that there is no heat transfer from the fluid to the wall of the viscometer. If the heat capacity of the fluid is 0.5 Btu/lbm. °F = 2.14 kJ / kg °C, how much does the fluid's temperature rise?
