Question

Kinematic viscosity of air at 20⁰ C is given to be 1.6 $\times$10^–5 m²/s. Its kinematic viscosity at 70⁰ C will be varying approximately:                                                                                                                                                     

      (a) 2.2 $\times$10^–5 m²/s                                               (b) 1.6 $\times$ 10^–5 m²/s

      (c) 1.2 $\times$ 10^–5 m²/s                                               (d) 3.2 $\times$10^–5 m²/s
