Question

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 700 kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind?

(The formula for P as a power function of v is P = a ⋅ v3.

A. 88 kW

B. 175 kW

C. 125 kW

D. 1050 kW

Answer:New power = 88 Kw (Approx.)

Step-by-step explanation:Given:P = a(v³)

Old power p = 700 Kw

Old wind speed v = 12 m/s

Find:New power when v = 6m/s

Computation:P = a(v³)

700 = a(12³)

a = 0.4050 m²

New power = a(v³)

New power = (0.4050)(6³)

New power = 87.48

New power = 88 Kw (Approx.)
