In a geothermal power plant, the used geothermal water at 80°C enters a 15-cm-diameter and 400-m-long uninsulated pipe at a rate of 8.5 kg/s and leaves at 70°C before being reinjected back to the ground. Windy air at 15°C flows normal to the pipe. Determine the average wind velocity [km/hr]. Assume that the pipe surface temperature is equal to the water temperature and that radiation heat transfer can be neglected.
