Question
I need help figuring out the remaining parts; also do step-by-step, which is very helpful.
Transcribed Image Text: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.

Expert Solution
Step 1: Introduction
To calculate the
- friction factor for 7.8 in pipe
- pressure drop for 7.8 in diameter pipe
- mean velocity of the 7 in pipe
- Reynolds number for 7 in pipe
- friction factor for 7 in pipe
- pressure drop per mile for 7 in pipe
flow rate of the 7.8 in pipe = 2.4 ft3/ sec
diameter of the pipe, d1 7.8 inch = 0.198 m
diameter of the pipe d2 7.8 inch = 0.177 m
2.4 ft3/ s=0.067 m3/ sec
