A 6.2-mm-diameter electrical transmission line is exposed towindy air. Determine the drag force exerted on a 165-m-long sectionof the wire during a windy day when the air is at 1 atm and 15°Cand the wind is blowing across the transmission line at 65km/h.
The density and kinematic viscosity of air at 1 atm and 15°C areÏ = 1.225 kg/m3 and ν = 1.470×10-5m2/s.
