2. A 2.2kg block of ice initially at -20°C is immersed in a very large amount of liquid nitrogen (LN) at - 196°C (which is the boiling point of LN), and the nitrogen and ice are allowed to come to thermal equilibrium. a) Draw complete energy diagrams for the problem, and determine how much LN is converted to gas (vapor). Note: the emphasis on \"very large\" implies that there will still be LN left when the two come to thermal equilibrium. b) The 2.2kg block of ice is removed from the LN and placed in a closed cup close to a heater. If the heater's power is 600Watts, how much time will be needed to melt the ice? Draw Energy diagrams to describe the situation. c) How will the diagram in b) change if heat is released from the cup to the environment at a rate of 30 J/sec? Write the new conservation of energy equation, but don't solve the problem.

Design an anaerobic digester to treat a thickened sludge with the following data: QT â€“ thickened sludge discharge rate = 370 m3/d, solids concentration (s) = 7%, MT â€“ sludge mass flow rate into thickener = 29,060 kg/d, SRT â€“ Solids retention time = 20 days, 70% of MT is organic matter, Rate of gas production in digesters for each kg of organic matter destroyed = 0.5 m3. Assume the sidewall height (H) = 14.5 m. Two digesters should be used so that the diameter of each digester is less than 20 m. The design should indicate the following: (a) Digester volume (in m3) and diameter (in m) (b) The total amount of gas produced from each digester at STP if only 60% of the organic matter is destroyed.

Your boss asked you to troubleshoot problems with a well stirred CSTR reactor in your company's chemical production plant. The problem with this 165 L reactor is that the conversion of reactant A is too low at $X_A = 53\%$. The reactor is heated by steam and the temperature of the liquid inside the reactor is 130°C. The initial concentration of A is 10 mol/L. The total flowrate of the liquid into the reactor is 5 L/min. The reaction rate data is given in the following table from a 1 L batch reactor conducted at a temperature of 130°C. t (min) CA (mol A/L) 0 10 1 9.4 5 8.1 10 6.4 15 5.3 20 4.7 25 3.7 30 3.25 35 2.8 40 2.4 45 2.3 a. Knowing that you should be able to compare the measured values with the rate data provided by the lab (given above), determine if there is a problem with this reactor. b. Based on your answer for (a) give a recommendation for improving the conversion of A
