JOHN Thank you for your comment.The main idea is to save electric cost.If i can calculate how much HP is produced by 3 cubic ft per sec water falling on turbine blades from ahead of approx 4 ft. This hieght can be increased to some extent.A set of heavy flywheels can be added to elongated turbine axles to increase power.Question is how can i calculate how much output this generates.Once this is known,i can go on to find how much water i can pump out by this power.Any additional quantity is a bonus and decreases the operational time of the electric pump to that extent,energy costs here are grizzly.There is lot of sunshine round the year,can a solar option be integrated in this system,will it be economical?All in all if i can draw out at least 1 cusec of water by this system,it will be a huge success and will benefit so many farmers who are working on desert soils and finding it difficult to make both ends meet due to high energy costs.
