###### Question details

Engineer Quincy Adams Wagstaff plans to design a piping system for a manufacturing process in a toothpaste factory. A certain pipe is to carry water at 68 deg F over a distance of 200 ft, with a pressure drop equal to 25 psia over that distance. The pipe is made of steel, and the specified characteristic surface roughness is equal to 0.0010 ft. Calculate the theoretical minimum required pipe diameter so that the flow rate equals or exceeds 12.0 CFM. If the pipe is available in varying sizes, in 0.125 inch increments from 0.5 to 6.0 inches I.D., select the proper pipe size for this part of the piping system.
