Recombinant protein is produced by a genetically engineered strain of Escherichia coli during cell growth. The recombinant protein can be considered a product of cell culture even though it is not secreted from the cells; it is synthesized in addition to normal E. coli biomass. Ammonia is used as the nitrogen source for aerobic respiration of glucose. The recombinant protein has an overall formula of CH1.55O0.31N0.25. The yield of biomass (excluding recombinant protein) from glucose is measured as 0.48 g g-1 ; the yield of recombinant protein from glucose is about 20% of that for cells.

a) How much ammonia is required?

b) What is the oxygen demand?

c) If the biomass yield remains at 0.48 g g-1 , how much different are the ammonia and oxygen requirements for wild-type E. coli that is unable to synthesize recombinant protein?

Identify a real-world problem in which the concept of a “thin film” and an "infinite slab" can be applied and turn in a copy of an appropriate problem statement.

Problem 1:

a. An incoming stream of 1500 lbmol/min consists of saturated water with 62% liquid water and 28% steam at 40 bar. This stream is heated at constant pressure to 700ºC. Using the steam tables, what is the heat transfer requirement for this step in kW?

b. This steam is then compressed isothermally to steam at 150 bar in a second step. What is the heat transfer requirement for this step in kW?

calculate the maximum velocity and the correspondingbvolumetric flow rate (in/cm^3/s) at which laminar flow of air and water is possible in pipes with the following diameter D=.25,.5,1.0,2.0,4.0,6.0, and 10.0in

Use the Peng-Robinson equation of state to compute the specific volume, V (L/mol), for methane gas at 298 K and 40 atm. Report your answer with 2 significant figures.

why can you write U (Internal energy) as a function of two thermodynamic properties and not all three (P, V, T)? Why is the state fully specified by specifying only two properties? what is the internal energy state equation?

a steam compressor is operated sisaadly at 30 kpa with quality of 80% and leaves at 8.5 mpa 600c.the velocity of the steam going into the compressor is 1220 m/s.a heat loss of 50 kj/kg is occured during the process. based on the design the compressor has an inlet area of 50cm^2 and an exit area 120cm^2. answer all the following questions: a) list all given and required properties for each state. b) determine mass flow rate of the steam. c) calculate the outlet velocity. d) examine the power input to the compressor
