In the class, we discussed the use of Schaeffler diagram for microstructure study. If we weld stainless steel 304 to low carbon steel AISI 1018 using Autogenous GTAW weld, what composition will we obtain in the weld zone? Assume 50% dilution of base metals. Use the Schaeffler diagram provided below. Chemical composition of base metals are provided in the table below. Show your calculation and mark microstructure of 1018 and 304 and weld zone in the diagram. 30 Equivalent Nickel=%Ni+30(%C)+0.5(%Mn) 28 26 24 22 20 18 16 14 12 10 8 6 4 2 0 Austenite 0% 5% 10% 20% 40% 80% 100% A+M Martensite A+M+F M+F F Ferrite 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 Equivalent Chrome=%Cr+%Mo+1.5(%Si)+0.5(%Nb)+2(%Ti) Composition 1018 steel 304 stainless Chemical composition of steel plates (weight %) C Mn S P Si Cr Ni Balance 0.15-0.30 0.30-0.80 0.15-0.30 0-0.04 0-0.025 - 0-0.08 1.7 0.52 0-0.045 0-0.025 18-20 7.5 Fe

In a packed bed, the production of methyl ethyl ketone by catalytic dehydrogenation of 2-butanol takes place in the gas phase according to the reaction given below. Reactants are fed to the reactor at a pressure of 100 kPa. The reactor is operated isothermally at 300 °C. The feed is pure 2-butanol and its molar flow is 150 kmol/h. For a conversion of 95% in this reactor, calculate the required bed volume, reactor diameter, reactor size, catalyst amount, reactor volume, and their corrected values, ignoring the pressure drop in the reactor. Reaction: C4H10O -> C4H8O + H2; BM + H B: 2-butanol, M: Methyl Ethyl Ketone, H: Hydrogen PMP reaction rate expression: rp = mol/(1+KMPm)^2 kg-kat.h where P, PM, and P are partial pressures. Bulk Density: 1425 kg/m^3 Bed porosity (εg): 0.39 mol/(kg.cat.kPa) T: Kelvin Keq = 100^(1-T/1000) * exp(-10000/T) (T: Kelvin) NOTE 1: If it is necessary to calculate numerical integration, calculate by taking the integration step interval as 0.05. Note 2: Go to the solution by calculating the volumetric flow rate without assuming the L/D ratio.
