For a good example of a typical, practical, chemical engineering field application of Excel, go to: http://www.cheresources.com/invision/topic/20114-partial-volume-horizontal-tank-height-calculation/#entry83149
This is a real world engineering application of a spreadsheet to solve an on-going problem in industry. And there are thousands more of similar applications out there! Don’t forget: the original spreadsheet invention (Lotus 1-2-3) was made to attack and resolve the 3 outstanding basic needs of engineers:
- Make accurate and quick calculations;
- Make graphical representations of data and results (graphs, curves, etc.)
- Make engineering sketches and drawings.
Today, Excel can do all that and much more with the programming tools introduced with VBA (Visual Basic Applications). Also, don't forget that a spreadsheet is basically a Flat Database - a means to store information for retrieval and use in on-going calculations.
