Question 1 Answer saved A wind turbine produces 779.1 kW of power when the wind blows with a speed of 8.2 m/s. How much power

science physics

Answer 1

Answer #1

Given

Turbine power P1 = 779.1 kW
wind velocity v1 = 8.2 m/s
Power of turbine P2 =?
wind velocity v2 = 5.4 m/s

We know that the power of a wind turbine is

P = (0.5*rho*A*V^3)

here the power P is proportional to cube of wind velocity

P2/P1 = (V2^3/V1^3)

P2 = P1*V2^3/V1^3

P2 = (779.1*10^3)(5.4)^3/(8.2)^3 W

P2 = 222.50 kW
The turbine will produce 222.50 kW power
