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
Answer : 1. Its depends on the density ( Force ) of the air
Pls explain wit Formula sir
