I am designing an in-vessel composting system - a 21 ft. long 4 ft. diameter steel tube that is mounted and spun on wheels by a hydraulic pump/turbine assembly, coupled to a 60:1 gear reduction box - the hydraulic pump will likely be powered by a small 4-5 HP gas powered motor.
My question relates to calculating the necessary torque to spin this vessel, and how to determine how much speed is altered. The vessel weighs probably 2000-3000 lbs. and will hold probably up to 2000 lbs. of compost.
How can I calculate the necessary torque to spin this? I suspect it has something to do with the circumfrence, the radius from the axis of rotation, etc., but don't really know how it all fits together.
Thanks!
