Question: a water treatment plant pumps water into a distribution system...

Question details

A water treatment plant pumps water into a distribution system at a rate of 70,000 gpm anda pressure of 70 psi. The pipe has a diameter of 30 in. and is made of galvanized iron Estimate the pressure 700 ft downstream of the treatment plant if the pipeline remains horizontal. Use the Colebrook equation to determine the friction factor Compare the friction factor estimated using the Colebrook equation to the friction factor estimated using the Swamee-Jain equation and Moody diagram. Submit a copy of the Moody diagram showing how you used it to determine f After 20 years in operation, scale buildup is expected to cause the equivalent sand roughness of the pipe to increase by a factor of 10. Determine the effect on the water pressure 700 ft downstream of the treatment plant. Use Swamee-Jain to determine friction factor. a. b. c.
