Explain the reason why the wake of a horizontal axis wind turbine at normaloperating conditions shows an expansion downstream of the rotor disk.ABCDEA.B It is a direct result of mass & momentum conservationB.If we double the diameter of a wind turbine and every other aspect of its design,hypothetically, stays the same, what is the expected effect on its rated power?C.It is due to the effect of turbulenceIt is a direct result of momentum conservationD.It is due to the slow-down of the wind on the bladesE.It is because of the unsteady flow over the bladesit is due to the rotation axis of the wind turbine, horizontal vs verticalWill stay the sameWill be halvedWill increase in a cubic wayWill doubleWill quadrupleE. It will quadruple. Power is proportional to the area so if the diameter goes up by afactor of 2 the power will go up 4 times.
