CoalCoal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

How to Calculate the Coal Quantity Used in a Power Plant · Coal trader's web sites give base prices in the international market. We take a coal price of around 65 / Ton. The cost of coal consumed by 100 MW power plant is ( x 65) 3497 /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) cents per unit.

How to implement the FFT algorithm · Next concern is the amount of data you're going to send to the FFT and the sample rate. The sample rate must be a 2^N number, but you don't need to send an array of 2^N samples to be processed (read the NR for different implementations). You can just send 50 samples, for example, and fill the remaining array with 0s. But remember, the more data ...
