cable will puncher for many reason, i.e. m/c digging , jcb excavation for unknown area, surrounding the cable not protect properly so that outer load impact come to side

When two core (two Phase) are come into contact,the cable burst.
so that under ground cable go into depth 2.5 mt approx.otherwise laying in Hume pipe. Awareness of cable rout must known to all agency before working.

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?
