Dear sir, I am working in wind mill division , pls explain Pls explain in details with formula My question is Wind speed 3.5 M/s Gen RPM is 1500 ( 25 K/w Production ) Wind speed 12 M/s Gen RPM is 1500 ( 220 K/w Production ) Why in 3.5 m/s generation was low , why in 12 m/s generation was high , Pls dont explain wind force or wind density , that one already i know For the above question RPM was same why the KW was different Answer : 1. Its depends on the density ( Force ) of the air Sir , Pls explain wit Formula sir1 1719
