My grandfather and I are running some experiments down the river, however we don't have expertise in engineering so I bring up this question to the community and hope someone could help.
How many kWh a turbine with the following features would generate?
These images are just a simple prototype which does not apply some of the following features:
Diameter: 1.20m. (Including its palettes and axis which has the thickness of 20cm.)
10 Longitudinal/helical palettes with length of 1.50m., thickness of 2cm. and height of 50cm.
Total weight: 50kg. (Palettes and axis included for torque boost.)
Flow rate (amount flowing through the device): 3m³/s
Flow rate: 209.000 m³/s
Speed: 2 meters per second.
It would be installed 2 meters beneath the river surface, placed horizontally.
