Section 3: Farm Power

Sources of Power

Subtopic: Sources of power on the farm – human, animal, mechanical, electrical, wind, solar and biomass

Question Statement:

The power developed by an agricultural wind rotor is proportional to the wind velocity $V$ raised to the power:

Options:

  • (A) 3 (cubic relationship $P \propto V^3$)
  • (B) 2 (quadratic relationship)
  • (C) 1 (linear relationship)
  • (D) 0.5 (square root)

Answer Key:

A

Step-by-Step Solution & Explanation

Wind kinetic energy flux is $P = \frac{1}{2} \rho A V^3$, so available power scales cubically with wind speed.
