Now that we have the power in watts, we can convert this value to kilowatts by dividing by 1,000: Power = (frac{44,263.04 mat{,W}}{1,000}) Power = (44.263 mat{,kW}) The water wheel could have produced approximately 44.263 kW of power.
In Fig. 3, Fig. 4 the data is presented in order to show the effect of the fresh feed size, particularly the % −6″ +1″ (−152 +25 mm), on the SAG mill power consumption (Pc) in kW and on the SAG mill specific energy consumption (Ecs) in kW h/t, obtained by dividing the power consumed (kW) by the fresh feed rate (t/h).
In the following analysis capacity, T, is expressed in short tons per hour, tph, and power consumption, P, in kilowatts, kw. Accordingly power consumption per unit of capacity, Po will be expressed in kilowatt hours per short ton, or kw-hr per ton. ... In other words, the capacity should be proportional to the mill speed raised to power m, the ...
Is wind power right for you? Find out quickly with our wind power calculator. Simply provide the data requested and you'll instantly know how practical a wind turbine system would …
Here is how we can calculate how many kW you would need for this flat: Air Conditioner kW Capacity = 100 m 2 × 0.065 kW per m 2 × 1.12 (ceiling height correction) × 1 (average climate) × 1.1 (very sunny correction) + 1.2 kW (kitchen included) = 9.2 kW. For this 100 m 2 flat, you would need about 9.2 kW of cooling output. Getting a 10.5 kW ...
