What is the difference between multimeter
1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
