H. Computer Spreadsheet Problems

H1. Use a spreadsheet to solve Problem 2.D.16, but with iso-butane replacing n-butane.

See Appendix B for Chapter 2 before starting on this problem.

H2. Show that the spreadsheet in Figures 2.B-3 and 2.B-4. has convergence difficulties if Goal Seek is used to make cell B19 (Σxi = 1) equal 1 by changing cell B9 (V/F).

H3. A feed containing 30 mol% isobutane, 25% n-pentane, and 45% n-hexane is flashed at a drum pressure of 50 psia and drum temperature of 650°R. Find V/F, liquid mole fractions, and vapor mole fractions. Use Eq. (2-30) and parameters in Table 2-3. Use a spreadsheet to solve this problem. (Turn in two copies of the spreadsheet—one with numbers in the cells and one with equations in the cells.)
