Pressure at end of pipe with 14 gpm flow

[gribblepig]

I am trying to learn how to calculate pressure at the end of a pipe. The pipe is 2" PVc and has a flow rate of 14 gpm at teh end of a 35' run from the pump. How do I calculate pressure at this point?

What kind of pressure? Static pressure at the end of an open pipe is zero.
