Use the value of the viscosity of water given in Table B.2

Chapter 1, Problem 1.72

(choose chapter or problem)

Use the value of the viscosity of water given in Table B.2 at temperatures of 0, 20, 40, 60, 80, and \(\mathrm{100~^\circ C}\) to determine the constants D and B which appear in Andrade’s equation (Eq. 1.11). Calculate the value of the viscosity at \(\mathrm{50~^\circ C}\) and compare with the value given in Table B.2. (Hint: Rewrite the equation in the form

               \(\ln \mu=(B) \frac{1}{T}+\ln D\)

and plot \(\ln \mu\) versus 1/T. From the slope and intercept of this curve, B and D can be obtained. If a nonlinear curve-fitting program is available, the constants can be obtained directly from Eq. 1.11 without rewriting the equation.)
