It is generally accepted that practical mill power PM is a function of mill capacity and diameter, i.e.,P M Mill Constant Mill Diameter n where n 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM K b LD 2.5 where k is a proportionality constant.

Nov 09, 2020 Wind turbines commonly produce considerably less than rated capacity, which is the maximum amount of power it could produce if it ran all the time. For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year less if the wind isnt blowing reliably.
