A long 8-cm-diameter steam pipe whose external surface temperature is 908C passes through some open area that is not protected against the winds. Determine the rate of heat loss from the pipe per unit of its length when the air is at 1 atm pressure and 78C and the wind is blowing across the pipe at a velocity of 50 km/h.
