Calculate the viscosity of saturated liquid water at 0 °C and at 100 °C (at atmospheric pressure) using Eq. 1.7-1, and express the results in mPa·s. The density of liquid water at 0 °C is 0.99987 g/cm³ and at 100 °C is 0.95865 g/cm³. b. Compare the results with the experimental values in Table 1.4-1.
