Thanks for the responses, sorry for my impatience its my first post and this is a new world of communication for me and most engineers (no plans). In FHWA HEC 14 I found an equation for circular conduits which calculates a d50 and I only needed the dia, velocity, and T.W. depth (which I assume...
The rip-rap is called for at the outlet headwall of the 8" siphon pipe. The channel is kinda narrow at this point, so excavating a pool seems stupid when first we want positive drainage, and second there is already a pool of water not too far downstream caused by a road culvert.
This is all I...
What reference do I need to size this rip-rap based on the given info. In more technical terms energy dissipation for an abnormally high velocity and small pipe size using rip-rap as the means.
The only thing you can control is the working environment. Make sure that you are around the EI's a lot. I almost share a cubicle with a 63 year old engineer, so It doesn't get much better than that as far as training. And this also works better for him, since he's always aware of what I'm...
For a dam project I have an 8" siphon pipe flowing at 15 cfs and roughly 40 cfs. I can't use the standard nomograph to size the rip-rap, because 8" isn't shown, and the graph says clearly "do not interpolate". Our original design is to have the pipe at a concrete headwall (and plenty of...
