A 6-mm-diameter electrical transmission line carries an electric current of 43A and has a resistance of 0.002 ohm per meter length. Determine the surface temperature of the wire during a windy day in °C when the air temperature is 14°C and the wind is blowing across the transmission line at 40kmh. Write your answers in 2 decimal figures. Use the Churchill and Bernstein correlation.
