A solvent-extraction operation is carried out continuously in a plate column with gravity flow. The unit is operated 24 h/day. A feed rate of 1500 ft3/day must be handled 300 days per year. The allowable velocity per square foot of cross-sectional tower area is 40 ft3 of combined solvent and charge per hour. The annual fixed costs for the installation can be predicted from the following equation:
where Fsf = cubic feet of solvent per cubic foot of feed. Operating and other variable costs depend on the amount of solvent that must be recovered, and these costs are $0.04 for each cubic foot of solvent passing through the tower. What tower diameter should be used for optimum conditions of minimum total cost per year?
Which do you think would be the greater health hazard: the release of a radioactive nuclide of Sr or a radioactive nuclide of Xe into the environment? Assume the amount of radioactivity is the same in each case.
A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoe..

Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
Hydrogen is manufactured from methane by either steam reforming (reaction with steam) or partial oxidation (reaction with oxygen). Both processes are endothermic. What reactor temperature and pressure would you expect to be optimal for these proce..
How might the CHPL be utilized by a health care informatics professional who is considering the purchase of an EHR for an ambulatory practice and What additional resources would you suggest?
When dilute nitric acid was added to a solution of one of the following chemicals, a gas was evolved, This gas turned a drop of limewater, Ca(OH)2, cloudy, due to the formation of a white precipitate. The chemical was
The air-film coefficient at the outside of the insulation may be assumed constant at 2.0 Btu/(h)(ft2)(°F) for all insulation thicknesses
The reactor is jacketed by water at a temperature of 200C. The overall heat transfer coefficient has been estimated at 300 J/(m2.s.K), while the heat transfer area is 0.75 m2. Mixing is ensured through an agitator, which contributes a work of 12 KW..
