Pulling Cable in Trench
Pulling Cable in Trench
(OP)
Could anyone share info on the coefficient of friction for pulling PVC jacketed cable on sand. I've had no success with the resources available to myself.
Thank You,

Why not get a chunk of the cable just drag it trough some sand? Put a scale on it and drage it through dry and wet sand. I would drag a couple of lengths at different speeds to see variations of tensions with length.
Check the static and dynamic friction.
I don't think you'll get a friction factor in the classic sense. It's going to be a rolling resistance of sand grains to sand grain and will vary with the type and size of sand. It will also vary with the wetness of the sand.
You may have to schedule a field trip to the beach.
I would think sand would have a low friction and be easy to pull through----but then there was that 40 yard sand crawl our DI liked us to do so much. It looked easy until the first time I did it.

Lots of places with sand and no snow.
Florida, Hawaii, Aruba, Virgin Islands
See you travel agent.
