Dynamic viscosity of water µ(10-3 N • s/m2) is related to temperature T (°C) in the following manner:
T | 0 | 5 | 10 | 20 | 30 | 40 |
μ | 1.787 | 1.519 | 1.307 | 1.002 | 0.7975 | 0.6529 |
(a) Plot this data.
(b) Use linear interpolation to predict i at T = 7.5 °C.
(c) Use polynomial regression to fit a parabola to the data in order to make the same prediction.
