Assignment 2a - hopper design
You can use this excell file as a starting point. I give it to you because it has turned
out that if I don't many student have more problems with proper implementation of
the problem in excell than with the hopper design problem itself. So please use this.
In the sheets 'overview' and 'walltest' you find the basic data.
Most helpfull will be the sheet 'test(1)'. You can use this sheet for the evaluation of
one of the four tests. To use it for the others, make copies. Don't copy parts of this
sheet to new sheets, but copy the sheet as a whole (right click the 'tab' of the sheet,
select 'move or copy', choose 'copy' etc. ) and put the data in the new sheet.
Before makning other changes in sheet 'test(1)' try to change the values in the red cells
(actually you don't have to make other changes in this sheet)
After having made a copy of 'sheet(1)', in the new sheet you can or have to change
the green cells
