WebNov 15, 2015 · Let's compare this with the theoretical A v 3 , as described e.g. in MacKay, Sustainable Energy -- without the Hot Air p 263 ff. Consider the effects of A and v 3 on power separately: A: the two wind turbines here have rotor diameters 101 and 141m, so A ratio ~ 2 but max power ratio ~ 1.4. WebThe power ratio (Equation 9.9) with ND 2 constant can be manipulated into Equation 9.24 which predicts a decrease in power on scale up with the inverse of the impeller diameter. For a hypothetical 10‐fold increase in impeller diameter, then, only 0.1 of the small scale power input would be required. [9.24] View chapter Purchase book d3fe bus
