in an experiment with an Ostwald viscometer, the times of flow of water and ethanol are 80s and 175s at 20C. the density of water is 0.998g/CM3 and that of ethanol is 0.790g/Cm3. the viscosity of water at 20C is 0.01008poise. calculate the viscosity of ethanol

Step 1
The formula used is: \[ \frac{\eta_1}{\eta_2} = \frac{\rho_1 t_1}{\rho_2 t_2} \] where \(\eta\) is the viscosity, \(\rho\) is the density, and \(t\) is the time of flow. The subscripts 1 and 2 refer to water and ethanol, respectively. Show more…

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 g/cm³ takes 35 seconds. Taking the density of water at 20.2°C to be 0.9982 g/cm³, calculate the viscosity of the other liquid if the viscosity of water at this temperature is 10 centipoise.

When 10 mL of water at 20°C is placed in an Ostwald viscometer, it takes 136.5 s for the liquid level to drop from the first mark to the second. For 10 mL of hexane at 20°C in the same viscometer, the corresponding time is 67.3 s. Find the viscosity of hexane at 20°C and 1 atm. (ηH2O = 1.002 cP, dH2O = 0.998 g/cm³, dC6H14 = 0.659 g/cm³)

The viscosity of liquids decreases with increasing temperature. The empirical equation η(T) = Ae^(E/RT) provides the relationship between viscosity and temperature for a liquid. In this equation, A and E are constants, with E being referred to as the activation energy for flow. What would be the ethanol viscosity at 0.0 °C, if its viscosities at 20.0 and 40.0 °C are 1.144 and 0.794 cP?
