I think you are right perhapes, but the potable water rarely uses cast piping, otherwise you could give this theme sponor your refereces of your compang. I mean the solution of the question is that you must consider the economical total.High speed means high energy lose, although it could reduce the pipe size

  "sizing" and "design velocity" of piping. As a start and for the specific applications you note, you may wish to obtain some basic references (e.g. see the couple, specific references noted in the thread at <a href="http://www.eng-tips.com/viewthread.cfm?qid=133700&page=4">http://www.eng-tips.com/viewthread.cfm?qid=133700&page=4</a> ), basic standards (e.g. ANSI/AWWA) and manufacturer's manuals, as well as search the archives of this and other forums as you wish. With all the choices of materials, dimensions, properties, and also in some cases conflicting information out there today with regard to same, to do this right for the ultimate long-term benefit for an Owner, taxpayers, and the environment probably requires all this, as well as perhaps a good bit of experience and perhaps integrity as well. I think reputable "civil", other engineers, and others working for consultants and utilities make a living out of doing this and other engineering work.
