Hi everyone,
Just a couple important notes from issues that came up in lab today:
A) On the Excel file, question 2, the first line is supposed to be an example. However, it is incorrect on two counts. First, the data you inserted from rainfalldata.xlsx has rainfall data for 1/1/12, and that should be included in your calculations. Second, "Outputs" (column E) and "Amount supplied by the municipal supply" (column H) are incorrect for that day. The outputs in ft^3 should have a value of 1604 (but be sure to show your work, 0 credit will be given for typing that number).
B) It has now been fixed, but if you downloaded a copy of today's lab lecture notes before around noon today, there's a typo on the 4th slide: the volume of the cistern should be calculated as 15000+750*LettersLastName, not 1500+ 750*LettersLastName. Sorry for the confusion, if you see any other such contradictions, please ask for clarification - we do make mistakes!
C) The rainfall.xlsx file has two tabs: one has the precipitation in inches, the other tab has different units. You'll get the same answer if you use the correct conversion for each case, but please be aware of the difference - starting with the values in the inches tab will be easiest.
D) Please note (as the instructions do) that for question 3, the x and y axes should be labeled, and that you need two separate plots. In the example, the x-axis is day of the year, but there are many ways to display the date, you may choose a different one.
We've also gotten a few questions about the lab feedback on BBLearn: when you look at the assignment on BBLearn, the preview you see is for what you submitted, not our responses. To see the responses, click the file on the right side, should be a file starting with your last name and ending in "graded" or "grd"
Please let us know if you have any questions! We would much rather answer your questions before labs are due than take off points while grading.
