Water flows in a 75-m-long wrought iron pipe with a 0.20 m diameter and carries a discharge of 0.2


/s. The pipe is running horizontally and experiences a pressure drop of 120 N/ across its length. The temperature of the water is 25°C. (a) Compute and plot the velocity profile for this flow under the smooth pipe assumption. (b) Compute and plot the velocity profile using the rough pipe assumption. (c) Which profile (if either) is more appropriate in this case?
