A 12in diameter water main in your city has become very rough due to rust and corrosion, it has been suggested that the flowrate through the this pipe can be increased by inserting a smooth plastic liner into the pipe. Although the new diameter will be smaller, the pipe will be smoother. Will such a procedure produce a greater flowrate? List all assumption and show all calculations please!
