In a measurement of viscosity by Ostwald’s viscometer at 20.2°C, water takes 30 seconds to flow between the upper and lower marks while the flow of another liquid of density 1.500 gm cm –3 ,takes 35 seconds. Taking density of water at 20.2°C to be 0.9982 gm cm –3 , calculate the viscosity of the other liquid if the viscosity of water at this temperature is 10 centipoise.
