How to Determine the Yield of a Water Well
Testing your water well yield is the first step in determining quality of your water source. Contaminants can be treated and filtered but it matters little if your well runs dry. The EPA recommends annual testing to maintain the safety of your drinking water supply, but we rarely think about the actual amount of water available or your well yield.
· The use of coke increased iron production because it was stronger than charcoal and could support the weight of more raw materials, and thus furnace size was increased. The use of coke then spread to Continental Europe: Creussot, France in 1785; Gewitz, Silesia in 1796; Seraing, Belgium in 1826; Mulhiem, Germany in 1849; Donete, Russia in 1871; and Bilbao, Spain in 1880 ( Wakelin, 1999 ).

How To Calculate Process Yields – E&B Software
The FTY for D is 70/75 = .9333. The total first time yield is equal to FTYofA * FTYofB * FTYofC * FTYofD or .9000 * .8889 * .9375 * .9333 = .7000. You can also get the total process yield for the entire process by simply dividing the number of good units produced by the number going in to the start of the process.
