Wind Turbine Final
14 · 1919 that no wind turbine can convert more than 16/27 (59.3%) of the kinetic energy of the wind into mechanical energy turning a rotor. To this day, this is known as the Betz Limit or Betz' Law. The theoretical maximum power efficiency of any design of wind turbine is 0.59 (i.e. no more than 59% of the energy carried by the wind can

Estimation of shear rates inside a ball mill
Grinding slurries are known to be non-Newtonian. For such suspensions, slurry viscosity is not a constant, but is a function of shear rate. This study was aimed at the derivation of an estimate of a typical shear rate range inside a ball mill, in order to determine appropriate values of apparent viscosity for studies of the effects of rheology on grinding.
