| Data: fans with pressure specs. |
| Scenario: The "user" is an architect who can look up units and view their specs. We assume the user knows how much air flow is required for a room. The user specifies a length of air duct and a cross-section and is told whether a chosen unit has enough air flow and is shown the result of the simulation that shows the interior air flow pattern of the duct. |
| Implementation: Design the user interface - how the user views units, chooses one, specifies the duct, and views the results. Write a C or Perl program to extract the unit information. Write the HTML for the Web interface and the Perl program that is the CGI script. Write a Java applet that simulates the air flow in the duct cross-section and displays the result. |
