Air at 20 C flows over a 0.003 m diameter platinum wire in an anemometer. The readings indicate that the surface temperature of the hot wire is 80 C and the heat flux from the wire is 5000 W/m. Calculate the velocity of the air. Properties of air are provided below; Cp (kg/m) (J/kg-K) 1005 1.177 k (W/m.K) 0.0261 (m/s) 2.21 x 10-5 (kg/m-s) 1.85 10-5 (m/s) 1.57 x 10-5 8B/v (m-.K-) 13300 104
