Huskerduck, how many GPM on a 12" pipe with the outlet 10' lower than the inlet?

Wouldn't the length going down the back slope affect the flow?

Here's what my cost was for a system I put in the last couple days:

200' schedule 40 12" PVC

3-22.5 degree elbows and 1-45 degree elbow

A saddle for the 12" reduced to 3"

12" cap, that I may or may not use down the road

20' schedule 40 3" with a T, 90 degree elbow and a plug

2 seep collars

Glue and cleaner

Total cost $2,600
