Question

(a) With a of specific gravity 1.42 were 2.8 min and 5.2 minutes, respectively. The experiment was carried out at 30°C. Calculate the viscosity of the second liquid. Viscosity of water at 30°C = 0.80 cP; density of water at 30°C 0.9956 g/mL (b) A sphere of diameter 1.8 mm and density 2.75 g/cm2 falls at a constant velocity through large volume of the second liquid in (a). Calculate the time required for the ball to fall a distance of 90 cm through the second liquid given Ostwald viscometer, it was found that the times of flow of water and a second liquid
