1. Local and Average Convection Coefficients A fluid at a temperature of $T_{\infty} = 360 K$ flows past the upper surface of a solid plate at $T_s = 370 K$ to cool it, as shown below. The surface being cooled has a total length of $L = 2 m$ and a width (into the page) of $B = 1 m$. The local convection coefficient is of the form. $$h = Cx^{-1/2},$$ where $C$ is an unknown constant. The convective heat transfer from the upstream half of the plate is $q = 150 W$. a) Use the local convection coefficient to find the average convective heat transfer coefficient of the upstream half of the plate, $\bar{h}_1$. Leave your answer in terms of $C$. b) Use the heat transfer rate from the upstream half of the plate to find the average convective heat transfer coefficient $\bar{h}_1$. c) Solve for the constant $C$. d) Find the average convective heat transfer coefficient for the whole plate.

2. You will be given: a stock of 5X Bradford reagent (0.05% Coomassie G-250, 24% methanol, 42.5% phosphoric acid) a stock of 0.5 mg/mL BSA protein (might be a different concentration, check label) MilliQ water Calculate the amount of Bradford reagent, BSA, and water to add to each cuvette so that the final volume in each is 1.5 ml. DO THIS BEFORE CLASS. Record your calculations in your notebook. Hint 1: To determine how much Bradford reagent to add, do a C1V1 calculation. The final desired concentration of a solution is always 1x; this does not need to be stated. Hint 2: To determine how much BSA, do a separate C1V1 calculation. Make sure to convert stock concentration of BSA to the same units as the final desired concentration.

Use provided measured absorbance values of Escherichia coli and Bacillus subtilis at 28°C and 37°C to answer questions 1-4 on Microbial Growth (posted on HuskyCT) (2 points). 1. Bacterial growth rate must be determine from the log phase of the growth curve. Why? 2. List the remaining phases of the growth curve and briefly explain what is occurring in each with respect to the bacterial cells. 3. Does temperature affect the growth rate of the bacteria that was tested? If so, which temperature is optimal for growing E. coli? B. subtilis? Is there a difference in growth between the two organisms? If so, why? 4. What is the generation time for E. coli? B. subtilis?
