Acetone is to be recovered from an aqueous waste stream by continuous distillation. The feed contains 10 mol% acetone. Acetone of at least 95 mol% purity is wanted, and the aqueous effluent must not contain more than 1 mol% acetone. The feed will be a saturated liquid. Estimate the number of ideal stages required.
Develop a block diagram for such a shift register and briefly explain its operation.
Use the truncated virial equation along with the second virial coefficient calculated above to estimate the volume of water at 200 °C, 14 bar. How does this value compare with the volume obtained from the steam tables? Discuss this comparison.
Reconsider the Methanol Water Distillation. If the feed stream contains 60 mol % methanol, reevaluate reflux ratio, number of stages required, and the column diameter.
If oxygen is fed at 20 °C and 1 atm, what is the volume flow rate of oxygen to the furnace?
Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. Answer to the nearest integer.
Find an expression for the rate of appearance of glycerol, Ra, in the dog.
Suppose you discover after the combustion has been carried out that the thermocouple is not functioning properly. Use the final pressure gauge reading of 75.3bar to estimate the adiabatic flame temperature of cyclopentane. Do not assume ideal gas ..
What number should be in place of the 2 in the denominator for a spectrum to be emitted in the infrared region?
Calculate the mass percent of magnesium chloride in the mixture. Determine the minimum volume of silver nitrate that must have been added to ensure complete formation of the precipitate.
Does the total-product-of-labor function TP^1(1) = 32^2exhibit decreasing (marginal) returns to the fixed factor k? Why or why not?
Derive the Nernst potential for R+++ at equilibrium.
A 100-liter fed-batch fermenter was successfully operated for 200 h using an aeration rate of 14 l/s and a 5 W agitator. It is proposed to scale the fermentation up to 10,000 liters. What agitator power consumption is required?.
