A liquid (viscosity = 0.0016 N-s/m$^2$; density = 1000 kg/m$^3$) is forced through the circular tube shown in the figure below. A differential manometer is connected to the tube as shown to measure the pressure drop along the tube. When the differential reading, $\Delta$h, is 9 mm, what is the mean velocity in the tube? 2.6m 4 mm Density of gage fluid = 2000 kg/m$^3$ V = 0.027590 m/s

Question 4: Consider a solution containing 10.8 g of sucrose, $C_{12}H_{22}O_{11}$, and 25.4 g of water. If you were to use the same number of moles of sodium sulfate instead of sucrose in preparing the solution, how would the boiling points of the two solutions compare (same or different)? Explain (but don't calculate the actual boiling points). Hint: Think van't Hoff factors!

7. The free energy of a reaction is positive, i.e., greater than zero, indicating that this reaction cannot occur spontaneously or naturally. Do you think adding an enzyme to this reaction can cause the reaction to occur? Suggest a method you can employ thermodynamically to make this reaction occur. (Please provide detail explanation for your answers)

Exercise 2: (2.5 points) Let $X_1, \dots, X_n$ be independent identically distributed random variables with $E(X_1) = 2$, $Var(X_1) = 2(\theta^2 - 3)$ and $E(X_1^4) = 4\theta^4 + \theta$ with $\theta \ge 2$. Find a method of moments estimator for the unknown parameter $\theta$.

The reaction of burning of ethane is shown below: 2C2H6 + 7O2 -> 4CO2 + 6H2O The inlet molar flow rate of C2H6 is 1.5 mol/s, and that of air is 100 mol/s. The conversion of the limiting reactant is 75% and 90% of the fuel burnt combusts completely. Using the atomic balance analysis method: a) Draw and label the diagram of the given process (10 pts) b) Perform degree of freedom (DOF) analysis. (10 pts) c) Calculate the exit component molar flow rates. (20 pts) d) As a general rule, combustion processes are performed with an excess of air, but never with fuel in excess. Explain briefly (2-3 sentences). (10 pts) e) The specification of a process states that the "conversion of the fuel is 120%". Does this make sense? Explain briefly (2-3 sentences). (10 pts) f) Propose a way to increase the percentage of the fuel that undergoes full combustion. (10 pts) g) Give an example from everyday life or from the industry where the combustion process is used. (10 pts)
