    Betz' Law Experiments and Studies

      Definition

      Betz' law demonstrates the maximum possible energy or efficiency that may be gained by an infinitely thin rotor (ideal conditions) when a fluid is flowing through the thin rotor. According to the Betz' law, the maximum efficiency of a rotor or windmill is of 59.3 %.
