The variation of the dynamic viscosity of water with absolute temperature is given as

T, K                                     μ, Pa∙s
273.15........................1.787 × 10^-3
278.15........................1.519 × 10^-3
283.15........................1.307 × 10^-3
293.15........................1.002 × 10^-3
303.15........................7.975 × 10^-4
313.15........................6.529 × 10^-4
333.15........................4.665 × 10^-4
353.15........................3.547 × 10^-4
373.15........................2.828 × 10^-4

Using these tabulated data, develop a relation for viscosity in the form of μ = μ(T) = A + BT + CT² + DT³ + ET⁴. Using the relation developed, predict the dynamic viscosity of water at 50°C at which the reported value is 5.468 × 10^-4 Pa∙s. Compare your result with the results of Andrade’s equation, which is given in the form of μ = D∙e^B/T, where D and B are constants whose values are to be determined using the viscosity data given.
