A wind turbine with a blade diameter of 50 m, tower height of 60 m and wind speed of 10 m/s at ground level and the air density is 1.23 kg/m3 is operating. Calculate the actual power that can be harnessed from this wind turbine.
3. The wave heights h in the open sea depend on the speed v of the wind and the length of time t that the wind has been blowing at that speed. Values of the function h(v, t) have been experimentally determined and the results are recorded in feet in the following table. Here wind speed v is measured in knots and the duration t is measured in hours h(t, v)t 5 t-10 t 15 t 20 t 30 t-40...
