    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Definitely would love their input as well !

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Understood. It will only rotate a couple inches each turn, and rotate 1000s of times after loading, so I am not really concerned about a constant rotation speed while loading. Could you help me with the calcs for when its fully loaded and then I can look into the loading and unloading scenarios ?

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Once all buckets are added the system will rotate multiple (1000s) times fully loaded.

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    No this will only rotate in one direction.

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    There will be 40 buckets total @ 17.5 lbs ea. The buckets will be loaded from the side near the top (@ 8') one at a time, so the lift (up) side will only have 2-3 buckets before they rotate over the top and provide gravity pull on the down side. So I would think that power required would...

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Could we use a calculation that we have 5 degrees rotation in 15 seconds ? So a 2' diameter sprocket wound have perimeter = 2 * 3.14 * 1 = 6.28 ft 5/360 = .0139 rotations => .0139 * 6.28 = .087 ft = 1.044" traveled in 15 seconds => 0.0058 ft/sec ??

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Thanks Russ. The system only rotates 5 degrees, so the speed has to be very slow, but has no real required value.

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    The total weight of the chain will be 700 lbs. And the system is vertical. And no it will be rotating full buckets (it will load them one at a time so initially the weight will be small, and then once loaded it will rotate for 30 days as described below. And sorry about the gravity battery...

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    It will be turning pots full of liquid, equally distributed around the chain. And the sprockets may be lighter, I am using that as a safe base. Do not know much about motors yet, so wanted to figure out the power needed first. Rotation direction is always the same, and the weight is equally...

    I How to calculate the HP/torque required to rotate a dual sprocket/chain system?

    Hi, I am trying to determine the HP motor/torque that will be required to rotate the sprocket/chain system in the image below from a resting position. The sprockets will be at rest, rotate 5 degrees, come to a stop for 5 minutes, and then rotate again 5 degrees, repeated. The speed of...

    I What is the energy output of a Gravity Battery System?

    Thank you ! I am trying to understand the metrics behind Energy Vault or similar, where they use excess power to lift large concrete blocks with cranes to store the GPE, and then release and generate energy when needed by dropping the weights. Any ideas on how they can effectively generate...

    I What is the energy output of a Gravity Battery System?

    Would this be correct using the SI values and the joule --> kwh formula:

    I What is the energy output of a Gravity Battery System?

    OK so can I use the joule to kwh conversion on the SI values ?

    I What is the energy output of a Gravity Battery System?

    SI Unit calc: h = 15.24 m w = 2722 kg g = 9.8 m/s^2 GPE = 406536 Joules
