To determine the relative kinematic viscosity of acetone compared to water, an Ostwald viscometer with a 20 cm³ volume between marks was used. The passage times for each fluid were measured 10 times at 18°C, yielding the following results: t(acetone) = X s. t(water) = (4.4 ‡ 0.5) s. Knowing that at 18 °C the absolute dynamic viscosity, n, of water is 1055 x 10-5 poise and that the densities of acetone and water are 790 Kg/m3 and 1000 kg/m3, respectively, select the correct option: a) The time it takes for acetone to pass through the viscometer is 1.78 s. b) The relative kinematic viscosity of acetone with respect to water at 18 °C is: y (acetone)/y (water) = 2.48. c) The absolute kinematic viscosity of acetone at 18 °C is: y (acetone) = 1.33 x 106 m2/ s d) The absolute kinematic viscosity of water at 18 °C is: y (water) = 1.055 x 10-3 m2/ s
