1. A capillary tube viscometer as shown in Figure 1 is being used to measure the viscosity of an oil having a specific gravity of 0.85. T Fluid sample TD Capillary tube Figure 1: Capillary Tube Viscometer 2 The following data are apply; Tube inside diameter, D Length between manometer taps, L Manometer deflection, h Velocity of flow, v Determine the viscosity of oil if the manometer fluid is a mercury. = 2.5 mm = 300 mm = 177 mm/ = 1.58 m/s (10 Marks)
