is the prerecorded lecture from last year. The announcement referred to at the start of the video is now this page.
For the entire HW set:
Open coursepacks12withaudio.pptx Download coursepacks12withaudio.pptx and sphericaltankdepth.xls Download sphericaltankdepth.xls from Canvas/Files. Realize that sphericaltankdepth.xls is the answer. Your job, probably in another worksheet within the same file, should be to reproduce it using the following instructions in Jobs 1 and 2.
Job 1: Listen to coursepacks12withaudio.pptx Download coursepacks12withaudio.pptx pp. 53-70.
Job 2: Reproduce sphericaltankdepth.xls Download sphericaltankdepth.xls using pp. 60-70 of the PowerPoint file. This is problem 5 on p. 53 of coursepacks12withaudio.pptx Download coursepacks12withaudio.pptx. Send those results to me if not done already.
Job 3: Solve problems 1, 2, and 3 on p. 53 of coursepacks12withaudio.pptx Download coursepacks12withaudio.pptx using Polymath. If you have a Mac, use either Parallel Desktop or Amazon Web Services just like you did for DataFit, and see the instructions associated with Homework 3. To solve the problems in Polymath, use the NLE function. Click the f(x) = button to enter the equation. Insert a range to search for answers. Realize that the answers to #1 will be between -5 and 5, the answer to #1 will be between 0 and 1, and the answer to #3 will be between 0 and 0.1999 (If you get an answer of roughly 0.9, then you found a root that would result in a negative mole fraction.).
Job 4: Copy and paste the results from the sphericaltankdepth.xls Download sphericaltankdepth.xls file to a new file, edit the function in columns C, E, and G to be consistent with problems 1, 2, and 3 (in three separate worksheets). Put in new initial guesses that are based off of what you saw in Polymath for the prior problem.
Job 5: Put in the functions for problems 1, 2, and 3 into the edited worksheets, and solve via Newton's method.
Job 6: Lastly, do problem 6 on p. 53 (with further explanation on p. 54) of the PowerPoint file. You may want to see p. 84 of the PowerPoint file for this one, too. Your answer should be watergasshiftequilbrium.xls Download watergasshiftequilbrium.xls. Although not asked for, you could do this for one case in Polymath and get watergasshift.pol Download watergasshift.pol.
