Yes, my purpose is to lift water. I was searching on net to find ways to lift water and I found these ancient time water wheels.

I have one amusement park project where I need to lift heavy water at 200 feet height during amusement park time. Water may be like like 100,000-150,000 liter in one second from the ground pool where water will come back after processed in amusement rides/work etc.

I search how much big pumps I needed to lift this water and I found this general formula.

Pump HP = (height in feet * water flow in gallon per minute)/3960

https://www.easycalculation.com/physics/fluid-mechanics/water-horsepower.phphttp://irrigation.wsu.edu/Content/Calculators/General/Required-Water-Pump-HP.php**Normal pump**100,000 liter = 26,417 gallon

26,417 gallon x 60 = 1,585,033 gallon per minute

Pumps HP = (200 * 1,585,033) / 3960 = 80,052

Pumps KW = 59,694 KW Pumps (on 100% efficiency but this will be more at 80%)

Those might be 1000 pumps of 59kw if this formula is correct.

That is huge huge investment or huge power that's impossible for us to bear or install.

**Water Wheel Idea**Water wheel diameter = 74 meter

Water wheel diameter = 244 feet

Circumference = 765 feet

Two bucket at both side after every = 6 feet

Total buckets = 127x2 = 254

One bucket size = 4x4x4 feet (64 square feet)

Water in one bucket = 479 gallon

1 Bucket weight = 1,812 kg

Water lifted in one round = 121,603

Wheel speed: 1 round in 2 minutes

Round per minute: .50

Speed: 6.37 feet per second

Speed: 1.942 meter per second

Even this wheel is run by 200 kw motors that's good for us. For example 50kw motors installed at 4 sides to rotate wheel as fast as it can be with safety.

Conclusion:

Other than cost to construct this wheel, is this idea practicable? If not, scientifically what's problem in this idea. I mean same water wheel used thousands years before is constructed at big level and rotated with modern electric motors.

Please advice me.
