100 800 9 60 400 w 200 Wind Generator Energy Production Time

100 800 9 60 400 w 200- Wind Generator Energy Production Time (t) [min] 10 12

Solution

Solution :

The graph indicated energy vs time. SO at 8 minutes the energy by the turbine is 700 KJ. This is because if you draw a straight vertical line from x axis at 8, it will intersect at 00 KJ to the curve.

We know,

Power = rate of doing work = Work / time

TIme = 8 minutes = 480 seconds

Work = 700 KJ

Hence power = 700/480 = 1.4583 KW
