Wind Turbine Output کا حساب کیسے لگائیں
Wind Turbine Output کیا ہے؟
Wind turbine power output depends on wind speed, blade area, and efficiency. Power increases with the cube of wind speed.
فارمولا
Calculate: P = 0.5 × ρ × A × v³ × C_p
- P
- 0 — 0
- A
- swept area — swept area

- 1Calculate: P = 0.5 × ρ × A × v³ × C_p
- 2ρ = air density (≈1.225 kg/m³), A = swept area, v = wind speed, C_p = efficiency (~0.35-0.45)
- 3Typical 2-5 MW turbine: 5-15 GWh/year depending on wind resource

Typical utility turbine
عام غلطیاں جن سے بچنا ہے
- ✕Using peak power output instead of average capacity factor
- ✕Neglecting wake effects between turbines
اکثر پوچھے جانے والے سوالات
Why is wind speed raised to the third power?
Power proportional to kinetic energy (½mv²) and flow rate; combined gives v³ dependence.
How much area does a wind turbine need?
Large utility turbines need 2-5 acres minimum spacing; smaller residential turbines 0.5 acres.
