Water flows at a rate of 2.4 ft3/s in an old, rusty 7.8-in.-diameter pipe that has a relative roughness of 0.010. It is proposed that by inserting a smooth plastic liner with an inside diameter of 7.0 in. into the old pipe as shown in the Figure the pressure drop per mile can be reduced. Is it true that the lined pipe can carry the required 2.4 ft3/s at a lower pressure drop than in the old pipe? Support your answer with appropriate calculations. 7.8in. Old Pressure drop is a function of flow rate and roughness. What is the mean velocity for the current 7.8 in. diameter pipe?
