- TL;DR Summary
- figure out the total energy that a system of buckets, suspended on a chain system around pulleys, assuming the pulleys are 10 meters in radius, and that each bucket is 1000 cubic meters, falling for 30 meters. I used the simple mgh formula, but not sure how to factor in the radius. Also, how fast does the system have to run to produce maximum power and whether a gearbox might be used to take off power at slower revolutions

I am trying to figure out the total energy a system of falling buckets can produce, and whether it would be a system that can replace or enhance a system of turbines in a hydroelectric dam situation. I need to figure out the total energy that a system of buckets, suspended on a chain system around pulleys, assuming the pulleys are 10 meters in radius, and that each bucket is 1000 cubic meters, falling for 30 meters. I used the simple mgh formula, but not sure how to factor in the radius.
