Cylinder/piston pressure multiplier River water pump

[Matos de Mato]

Submersed water pump for river flows.
Two cylinders, one with 1 meter diameter and the other 0.2 m/diameter. Pistons are in the same shaft. Area ratio is of 25 X. The bigger cylinder have a shroud of a diameter of 1.5 meter in both ends and is open on both sides. When we submerse it in the river flow the water flows in and pushes the piston. On the other end of the cylinder the water flows out in the direction of the river flow.
The piston pushes the second piston, in a closed cylinder ( 0,2m/d) and pressures water. The inlets and outlets of this double side cylinder have retention valves to control aspiration and discharged of the cylinder.
The cylinders rotate on its axis, enabling continuous cycles.
I need to find the pressure on both cylinders, if the flows at 1 m/s, and power calculations if the pressure water works on micro hydro turbine to produce electric energy.

I would first consider the design and functionality of this cylinder/piston pressure multiplier river water pump. It appears to be a unique and innovative design that utilizes the natural flow of a river to generate power. The use of two cylinders, one with a larger diameter and one with a smaller diameter, allows for a pressure multiplier effect which increases the force and power generated by the pump.

In order to determine the pressure on both cylinders, we would need to consider the flow rate of the river (1 m/s) and the area ratio (25x). This means that the larger cylinder has an area 25 times greater than the smaller cylinder, resulting in a pressure increase of 25 times as well. However, the shroud on the larger cylinder may affect the flow dynamics and the actual pressure on the cylinders would need to be calculated using fluid dynamics equations.

The use of retention valves is also an important aspect of the design as it allows for control of the aspiration and discharge of the cylinders. This ensures a continuous flow of water and efficient operation of the pump.

In terms of power calculations, we would need to consider the pressure and flow rate of the water as well as the efficiency of the pump and the micro hydro turbine. The pressure and flow rate of the water would determine the amount of power that can be generated by the turbine, while the efficiency of the pump would determine the amount of power that can be transferred to the turbine.

Overall, this cylinder/piston pressure multiplier river water pump has the potential to be a sustainable and efficient source of electric energy. Further calculations and testing would be needed to determine the exact pressure and power output, but the design shows promise for harnessing the power of flowing water.
