Hmmm,

Say you are raising the water 100 feet.

Then, optimally, with 1 foot drop, you should be able to raise 1% of the water 100 feet.

For 5 feet of drop, you should be able to raise 5% of the water.

However, I'd anticipate your water wheels to be far from optimal. I don't have the efficiency numbers, but if the wheel is, say 20% efficient, then you would get the equivalent of 0.2% of the water flow being raised 100 feet per foot of drop.

Sorry man, I am not technical person, so please bear with me. []

Now I can understand something but I think since wheel should be made according to requirement using latest techniques to extract maximum force from dropping water that's why I assume it must should be at least 80%+. Because wheel does not have to lift water itself, wheel have to covert force to piston. If wheel lift water itself then there are chances of leaking water while lifting, incomplete water buckets, etc.

So if I assume 80% wheel efficiency and I want to calculate first wheel and last wheel in row.

Wheel efficiency = 80%+

Water lifting at: 200 feet

First wheel = Drop 1 feet (since pool is at 20' height so vertical distance is less between top pool-wheel)

Last wheel = Drop 20 feet (since pool is at 20' height so vertical distance is higher between top pool-wheel)

Now how much water both wheel can lift. Depending on your calculation I will calculate each wheel (20 in a row) myself.

Thank you for helping me.
