ASSIGNMENT 1 CHE 4273 Submit all files through learn.ou.edu. Including Simulation files. Make sure they can be opened before you submit. Sometimes students inadvertently submit corrupted files. DUE: February 12. PROBLEM #1 : This exercise is for sharpening your optimization skills. Suppose a flow problem on a pipe. F= 50 lbs/sec ρ =60 lb/ ft 3 μ =6.72 10 -4 lb/ (ft sec) η =0.6 (60% pump efficiency). -8760 h/year of operation Cost of electricity= \$0.05/ Kwh Cost of piping (\$/(ft year)) = \$5.7 [D(ft)] 1.3 Determine the optimal diameters and lengths of two pipes connected sequentially one after the other such that both are 2000 m long and a steady change of altitude of 15 meters. Ignore fittings. For this, you need to construct a total cost expression as a function of diameters and lengths. Can you get an analytical solution? How about solver in excel? PROBLEM #2 : An oil refinery has to blend gasoline. Suppose that the refinery wishes to blend four petroleum constituents into three grades of gasoline:
