pipe exit losses

[mechanicaldup]

Hi every one.
We are designing a water cannon system for cleaning purposes of a pit. Where can I get K-fators for pipe outlets/ nozzles to determine the exit losses?

I'd talk to vendors who provide the nozzles, they would have the overall nozzle resistance factors depending how they rate them.

Perhaps he is late for this answer but I had not entered this forum, if my memory serves me right one of publications where you can consult these values is "Manual Fluid-Flow" whose author is Crane, another publication is the "Cameron Hydraulic Data".
