Metabolic engineering Consider the engineering design of microbial cell culture and growth in the field of biotech- nology and metabolic engineering. Bioreactors are employed incorporating the use of bio- chemical substrates that provide essential chemical elements for the growth of the microor- ganisms. A typical stoichiometric representation of the aerobic growth of a microorganism with a defined chemical formula is shown below С, Н, ОН + а0, b NH, → cCH, No.15O04 + dH,0 + eCO, (C-source) (O-source) (N-source) (Microorganism) The ratio of moles of CO2 produced per mole of O2 consumed is called the respiratory quotient, RQ, which can be experimentally determined, and is therefore treated as a known quantity. To determine the theoretical yield of production (growth) of the microorganism, the stoichiometric coefficients, a, b, c, d are required. One can easily formulate an elemental mass balance for each of the four key elements. (a) Formulate an elemental mass balance for each of the four key elements. (b) Solve the system for RQ = 2.7.

P1A.6 The molar mass of a newly synthesized fluorocarbon was measured in a gas microbalance. is device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. e beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10Torr; for the same setting of the pivot, a balance was reached when CHF3 (M = 70.014 g mol−1) was introduced at 423.22 Torr. A repeat of the experiment with a di erent setting of the pivot required a pressure of 293.22 Torr of the uorocarbon and 427.22 Torr of the CHF3. What is the molar mass of the fluorocarbon? Suggest a molecular formula.
To evaluate the use of renewable resources, an experiment was carried out with rice hulls. After pyrolysis, the product gas analyzed 6.4% CO2, 0.1% O2, 39% CO, 51.8% H2, 0.6% CH4, and 2.1% N2. It entered a combustion chamber at 90 °F and a pressure of 35.0 in. Hg and was burned with 40% excess air (dry) at 70 °F and an atmospheric pressure of 29.4 in. Hg; 10% of the CO remains. a.

Hg and 400 °F?
Combustible vapor-air mixtures are flammable over a limitedrange of concentrations. The minimum volume % of vapor thatgives a combustible mixture is called the lower flammable limit(LFL). Generally, the LFL is about half the stoichiometric mix-ture, the concentration required for complete combustion of thevapor in air. (a) If oxygen is 20.9 vol % of air, estimate the LFL forn-hexane, C₆H₁₄.

Stress may trigger some headaches. This could be related to increased (hypertension) or decreased (hypotension) osmotic pressure in cerebrospinal fluid and inside the skull. The human body temperature also may be influenced by these changes. Calculate the pressure p ( in units of torr) inside the brain, if it resulted in 39oC fever. You need to assume a normal body temperature is 37oC, the average CP,m of the human body is approximated as 12.5R, and the outside pressure is 1 atm. Also, assume the process of giving the headache is adiabatic.

In the lungs, the respiratory membrane separates tiny sacs of air (absolute pressure=1.00x105 Pa) from the blood in the capillaries. These sacs are called alveoli, and it is from them that oxygen enters the blood. The average radius of the alveoli is 0.125 mm, and the air inside contains 14% oxygen, which is somewhat smaller amount than in fresh air. Assuming that the air behaves as an ideal gas at body temperature (310 K), find the number of oxygen molecules in one of the sacs.
