Gasoline (r 5 680 kg/m3 and n 5 4.29 3 1027 m2/s) is transported at a rate of 240 L/s for a distance of 2 km. The surface roughness of the piping is 0.03 mm. If the head loss due to pipe friction is not to exceed 10 m, determine the minimum diameter of the pipe.

Write a technical essay (maximum two pages) about stress concentration. and paste from the textbook. instead, read updated material about this phenomenon and provide a technical evaluation of the different techniques to avoid/reduce such phenomenon. consider in your analysis cutting-edge computational techniques such as fea to study and analyze stress concentrations.
