How to calculate maximum flow rate through a 12" pipe 3

[thien2002]

I am trying to figure out the maximum daily output for our 12" sewage piping to our wastewater basin. In order to calculate the maximum flow rate, what data do we need to include in our formula or what formula to use?

Thank you in advance for your help and contribution!

Does the Manning equation apply equally well to apipe intended to deliver gravity fed water?

 

[PEDARRIN2]

The Manning equation would apply with a different "n" factor based upon the pipe material.

You really need to read the "10 States Standards" now known as "Reccomended Standards for Wastewater Facilities". You may purchase it for about ~$10 or download it free here

You should never deviate from these standards without due cause. There are some minor errata, but this is the primary BOOK for all WW engineers. It is easy to read and very short.
