In recent years, Yantai City, Yantai City, vigorously develop the clean energy industry, especially wind power development is particularly rapid, at present, Yantai and grid operation of wind farms up to 28... Wind turbine
By the question, Q discharge = W electricity = 2.7 × 108kw?h = 9.72 × 1014J, q = 3.0 × 107J/kg,
∵Q discharge = mq,
∴ the need for the mass of standard coal:
m=
=
= 3.24× 107kg.
The answer is 3.24×107kg.
The answer is 3.24×107kg.
