An organic chemical is produced by a batch process. In this process, chemicals X and Y react to form chemical Z. Since the reaction rate is very high, the total time required per batch has been found to be independent of the amounts of the materials, and each batch requires 2 h, including time for charging, heating, and dumping. The following equation shows the relation between the pounds of Z produced (lb,) and the pounds of X (lb,) and Y (lb,) supplied:
Chemical X costs $0.09 per pound. Chemical Y costs $0.04 per pound. Chemical Z sells for $0.80 per pound. If one-half of the selling price for chemical Z is due to costs other than for raw materials, what is the maximum profit obtainable per pound of chemical Z?
For honey, which is Newtonian, the plot should be linear with the slope equal to the viscosity. Calculate the viscosity (or let Excel do it for you). Do a little Google or literature searching and see if you can find a value for the viscosity of h..
Suppose you pour a gallon of water on a yowling cat 10 ft below your bedroom window. (a) How much potential energy (ft · 1bf) does the water lose?
Consider that you are a senior consulting engineer and that you need to explain the topic in a written report to your customer, who is the managing director of a large company, and a commerce or law graduate.
A 25 wt% solution of coffee in water at 70°F is spray dried to a final moisture content of 5% (dry basis) with air that enters at 450°F and 1 atm with a humidity of 0.01 lb/lb (dry basis) and exits at 200°F. Assuming a reasonable value for the spe..
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.
The fictitious compound, pandemonium fluoride (PnF2) has a Ksp value in water of 3.091×10-9M3 at room temperature. Calculate the solubility of PnF2 in water. Express your answer in units of molarity.
Calculate the tower diameter and packing height and calculate NTU - Ammonia in air being absorbed by a pure water stream in a packed tower.
Due to upstream process modifications, the reactor feed has now changed from pure propane into a mixture that contains 50% nitrogen (by mol). If the reactor pressure remains at 5 bar, how should you adjust the temperature to achieve 95% conversion..
