Thank you so much professor bayan hussien sir.

Too much to discuss in this. You might also consider water wheels in lower gradient applications. This is a long document.

Thank you sir

The propeller blade should be oblique position and should be short and strong to strain the impact force by the water correct or fall. Then it should be well aligned and multiple blades should structured .

Ok.thank you sir .
