calculating water balances in a quarry

Depletion Method | Explanation | Formula | Examples

For example, depreciable value of quarry is $50,000 and total quantity of coal is estimated to be 500,000 then depletion rate is 10 cents per ton extracted. The complete formula to calculate depreciation using depletion method is: Depletion for current period = Units consumed this period: x Cost – residual value: Total units of natural resource: Example: Depletion method of Depreciation

Hydrate: what is it and how to calculate the percent of

2020-01-29 · Here is a setup of the calculation: Calculating amount of water in hydrate. From the calculation, you can clearly see that the units of g/mol in the numerator and denominator cancel out. Hence the percentage composition of water in CuSO 4.5H 2 O is 36.08 %. Now, you try: calculate the percent of water in borax, Na 2 B 4 O 7.10H 2 O. Ans: 47.24 %

Calculating Water Startup Time for Spiral Cases of

2013-03-01 · The theoretical calculation of water startup time has a higher degree of uncertainty and, for one component in the fluid column (the spiral or semi-spiral case) it is little more than a guess. The general equation for water startup time is adapted from the basic equation for water hammer or pressure transient, which in turn is also adapted from Newton’s Second Law.

How to Calculate Concentration - ThoughtCo

Sep 05, 2018 · Example: Determine the mole fraction of NaCl in a solution in which 0.10 moles of the salt is dissolved in 100 grams of water. The moles of NaCl is provided, but you still need the number of moles of water, H 2 O. Start by calculating the number of moles in one gram of water, using periodic table data for hydrogen and oxygen: H = 1.01 g/mol

Therefore the formula for calculating the strike water volume is: Strike water volume = weight of grain * desired mash thickness. For example, for a mash thickness of 1.25 qts./lb. (2.6 L/kg) and a grain bill calling for 10 lbs. (4.5 kg) of grain, the calculated strike water volume is 12.5 quarts (11.8 liters).

PREDICTION OF GROUNDWATER INFLOW AND HEIGHT OF THE

The unexpected water flows in large scale may reduce the production, delay the time of execution and danger the total mine safety (Hanna et al., 1994). When a pit penetrates in an aquifer, the significant amounts of groundwater flow occur to a pit. Therefore, the large volumes of water must be pumped to provide a dry mining
