2.5-L bench scale bioreactor is used for the production of recombinant P64K protein from Neisseria meningitides. The dimensions for the bioreactor are Dt 12.9 cm, ratio Di/Dt = 1/3 and N = 700 rpm.

A wind turbine has the maximum power output at the rated speed of 12 m/s and a rotor diameter of 82 meters. The cut-in and cut-out speeds for this type of wind turbine are 4 m/s and 23 m/s, respectively. The table below shows the annual wind data near a potential site for setting up a wind farm using this type of wind turbine and the power coefficient of the wind turbine at the specific wind speed.

11 Sunco Oil has refineries in Los Angeles and Chicago.The Los Angeles refinery can refine up to 2 million barrelsof oil per year, and the Chicago refinery up to 3 million.Once refined, oil is shipped to two distribution points:Houston and New York City. Sunco estimates that eachdistribution point can sell up to 5 million barrels per year.Because of differences in shipping and refining costs, theprofit earned (in dollars) per million barrels of oil shippeddepends on where the oil was refined and on the point ofdistribution (see Table 51). Sunco is considering expandingthe capacity of each refinery. Each million barrels of annualrefining capacity that is added will cost $120,000 for the LosAngeles refinery and $150,000 for the Chicago refinery. Uselinear programming to determine how Sunco can maximizeits profits less expansion costs over a ten-year period.

5.15. A small-parts assembly line involves the use of solvents requiring a high level of ventilation. To achieve removal of these toxic gases, a mean velocity of 8 ft/s must be maintained across the cross-section of a 12 ft high by 30 ft wide room. The toxicants are subsequently removed in a wet scrubber or filter, which causes a pressure drop of 30 lb/ft². Using a Cordier analysis, select the design parameters for a fan that will provide the required flow and pressure rise, while oper ating at or near 90% total efficiency, and that minimizes the diameter of the fan. Give dimensions and speed of the fan and describe the type of fan chosen.

PROPAGATION OF ERROR You are tasked to supervise the design of 0.5MW wind turbine to be constructed in a Wind Farm in Pililla, Rizal. Suppose the design criteria are as follows: The air density as surveyed after 2 year period averaged at 1.225 kg / cubic meter. The sweeping diameter of the rotor blades is 125m, and the anemometer reading in the area amounts to 4.2m/s on a 2 year period of survey. What is the theoretical power output of the turbine assuming 100% efficiency of operation? Your answer must be in kW and in two decimal places with correct signs. In the previous problem, if the diameter measurement is off by 0.1m and the anemometer reading is also fluctuating by 0.05m/s and if the error measurement for theoretical power output must be limited to 3%, WHY OR WHY NOT should you accept the design? * Show complete solution in paper.
