Question: Dynamic viscosity of water (10 3 N s/m 2 ) is related to temperature T(C) in the following manner: (a) Plot this data. (b)

Dynamic viscosity of water μ(10^–3 N · s/m²) is related to temperature T(◦C) in the following manner:

T O 1.787 5 1.519 10 1.307 20 1.002 30 0.7975 40

(a) Plot this data.
(b) Use linear interpolation to predict μ at T = 7.5 °C.
(c) Use polynomial regression to fit a parabola to the data in order to make the same prediction.

T O 1.787 5 1.519 10 1.307 20 1.002 30 0.7975 40 0.6529
