Jan 05 2016 The wood chips were successively ground in a hammer mill using screen sizes of 25.4 mm 10 mm 6.4 mm and 3.2 mm. The input power and the flow of material into the grinder were recorded continuously. The recorded power input vs. mean particle size showed that the Rittinger equation had the best fit to the experimental data.

The cut-in speed is the lowest wind speed at which a wind turbine begins to produce usable power. This varies for wind turbines. Cut-out speed. The cut-out speed is the wind speed at which the wind turbine stops being able to increase its power output i.e. even if the wind speed increases the power output will remain the same.
