A countercurrent system is to treat (on an hourly basis) 10 tons of gangue (inert material), 1.2 tons of copper
sulfate, and 0.5 tons of water with water as a fresh solvent. The solution produced is 10 percemt copper
sulphate (remainder water). After each stage. 1 ton of inert retains two tons of water plus dissolved copper
sulphate. How many stages are needed for a 98 percent of copper sulphate recovery?

A mixture of MgBr2 and inert material is analyzed to determine the Mg content. First the mixture is dissolved in water. Then all of the bromide ion is precipitated as AgBr by the addition of an excess of silver nitrate. MgBr2(aq) + 2AgNO3(aq) 2AgBr(s) + Mg(NO3)2(aq) In one experiment, a 0.8107 g sample of the mixture resulted in 1.1739 g of AgBr. Determine the percent (by mass) of Mg in the mixture.

Suppose that in an industry, workers are hired on an hourly basis. Labor costs are variable costs, in that the firm needs to hire more workers (for more hours) to increase production, and the firm can choose to hire zero workers if it does not want to produce. Suppose that market wages go up, and hiring workers becomes more expensive per hour, while other costs remain the same. Consider how this will affect the cost curves for a firm in...

A building has a calculated cooling load of 10 tons, of which 2.5 tons is latent load. The space is to be maintained at 72 F db and 50 percent relative humidity. Ten percent by volume of the air supplied to the space is outdoor air at 100 F db and 50 percent relative humidity. The air supplied to the space cannot be less that 55 F db. Assume barometric pressure at sea level, and using the Psychrometric analysis software,...

Pulp containing paraffin wax is to be dewaxed in a continuous countercurrent extraction system using kerosene. The pulp containing the wax is kerosene-free when entering the extractor, and contains 20% paraffin wax and 80% pulp. After extraction, it must not contain over 0.2 lb wax / 100 lb wax-free pulp. The kerosene used for the extraction contains 0.05 lb of wax per 100 lb kerosene. Experiments show that the pulp retains 2.0 lb of kerosene per lb of kerosene- and...
