Normal Depth

(OP)
Hi
I am wanting to know what direction I need to go with the Manning's equation to find the normal depth for a 60" diameter pipe with a discharge of 75 (n=0.012. the pipe has a slope of 1.20 percent. thanks any help would be great
 

RE: Normal Depth

Your discharge is 75_______. What gpm, cfs, acre feet per minute? Then set up a spreadsheet with the Mannings formula that gives you discharge by depth of flow. Start substituting until you get it.
