Question:
An Ostwald viscometer is calibrated using water at 20°C (η = 1.0015 cP, ρ = 0.998 g mL−1).
It takes 15.0 s for the fluid to fall from the upper to the lower level of the viscometer. A second liquid is then placed in the viscometer and it takes 37.0 s for the fluid to fall between the levels. Finally, 100. mL of the second liquid weighs 76.5 g. What is the viscosity of the liquid?
