Use the data in Problem P11-4A for the following reaction. Th elementary, irreversible, organic liquid-phase reaction is carried out in a flow reactor. An equal molar feed in A and B enters at 27ºC, and the volumetric flow rate is 2 dm3/s and CA0 = 0.1 kmol/m3. Additional information: (273 K) = 20 kcal/mol, (273 K) = 15 kcal/mol, (273 K) = 41 kcal/mol = = 15 cal/mol K = 30 cal/mol K k = 0.01 at 300 K E = 10,000 cal/mol (a) Calculate the conversion when the reaction is carried out adiabatically in one 500-dm3 CSTR and then compare the results with the two adiabatic 250-dm3 CSTRs in series. The reversible reaction (part (d) of P11-4A) is now carried out in a PFR with a heat exchanger. Plot and then analyze X, Xe, T, Ta, Qr, Qg, and the rate, –rA, for the following cases: (b) Constant heat-exchanger temperature Ta (c) Co-current heat exchanger Ta (Ans.: At V = 10 m3 then X = 0.36 and T = 442 K) (d) Countercurrent heat exchanger Ta (Ans.: At V = 10 m3 then X = 0.364 and T = 450 K)

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
