Appreciate the response. I knew there must be more to it. Making a lot of assumptions do you know of a way to get a general ballpark solution? I know the maximum amount of torque I can generate on the shaft so if it's order(s) of magnitude off I will know whether it is feasible to do.

I have a shaft within a pipe, all horizontal. Shaft diameter is 2.875" and pipe inner diameter is 5". Shaft and pipe length is 650 ft. Shaft weight is 2500 lb. I need to determine the torque needed to begin rotating the shaft. The coefficient of static friction between the shaft and the pipe is...
