Homework #1 Solutions 3.1 a. Let X1 =the number of hours of process 1 used X2 =the number of hours of process 2 used The objective is to minimize the cost of producing the three products A‚ B and C. The constraints are on the demand of each product. Min 4X1 + X2 subject to 3X1 + X2 ≥ 10 (A’s demand) X1 + X2 ≥ 5 (B’s demand) X1 ≥ 3 (C’s demand) X1 ‚ X2 ≥ 0 (nonnegativity) b. From the graph we can see that the isocost line just leaves the feasible region where the demand for C and B intersect. The

Solution to Tutorial 4 Given: F = 1000 kg-mole/hr‚ xF = 0.20 (ethanol is MVC) Feed is saturated liquid‚ thus q = 1.0 xD = 0.80‚ xB = 0.02 (maximum); R = 5/3 First‚ plot the equilibrium curve using the VLE data given. Note that you need to convert mole% ethanol into mole fraction. Then‚ apply the McCabe-Thiele method to find the number of theoretical (equilibrium) trays required for the separation. Step 1: Since R and xD are known (5/3‚ and 0.80 respectively)‚ plot the ROL equation - it
