(a) Using tabulated data for the viscosity of water and SAE 10 lube oil as a function of temperature, plot the data in a form that is consistent with each of the following equations:

(i) $\mu=A \exp (B / T)$

(ii) $\mu=a T^{b}$

(b) Arrange the equations in (a) in such a form that you can use linear regression analysis to determine the values of $A, B$ and $a, b$ that give the best fit to the data for each fluid (a spreadsheet is useful for this). (Note that $T$ is the absolute temperature here.)
