I need some help with calculating the wetted perimeter for pipes in my TC calc. I have pipes starting at 18" (upstream end) diameter, then 24" and 30" at the pond end.
I am somewhat confused by how to calculate for each pipe plus need to know if I average the combination of the three sizes for the TR55 worksheet. I would appreciate any help in a basic explanation or spreadsheet etc for a drainage dummy.
Thanks
