In the spring of 2003, SARS (Severe Acute Respiratory Syndrome) spread rapidly in several Asian countries and Canada. The total number, $P(t)$, of SARS cases reported in Hong Kong by day t, where t = 0 is March 17, 2003, can be modeled using the following logistic function: $P(t) = \frac{1952}{1 + 11.67e^{-0.147t}}$ Round your answers to the nearest tenth! (a) What limiting value of $P(t)$ does this model predict? cases (b) In early April 2003, there was fear that the disease would spread at an ever-increasing rate for a long time. What is the earliest date by which epidemiologists had evidence to indicate that the rate of new cases had begun to slow? days after March 17, 2003

6.5 A baffled fermenter tank, 5.0 ft (1.525 m) in diameter, which will contain 1600 gal (6.056 m³) of a beet-sugar solution, will be used to produce citric acid by action of the microorganism Aspergillus niger at 25°C. The vessel will be agitated with two 28-in-diameter (0.71-m) flat-blade disk turbines, one located 2 ft (0.61 m) above the bottom of the tank, the other 6 ft (1.83 m) from the bottom, on the same shaft, turning at 92 r/min. Sterilized air will be introduced below the lower impeller at 2.1 ft/min (0.01067 m/s) superficial velocity based on the tank cross-sectional area. The solution sp gr = 1.038, the viscosity 1.4 cP ($1.4 \times 10^{-3}$ kg/m \cdot s). (a) Estimate the agitator power required. Ans.: 5.4 kW. (b) If the air is introduced through five $\frac{1}{2}$-in, schedule 40, open pipes (ID = 0.622 in = 15.8 mm), estimate the power imparted to the tank contents by the air.
