- Geozip
Geozip is a Perl program for calculating the distance between two zip codes in the United States. The sub-routines included in the code can be used to calculate any distance between latitude and longitude coordinates. The package includes data for the US, the script, including two sub-routines, one gets the coordinates and city name, the other calculates the distance between two points. The result should have a precision of about 50 meters, because the calculation takes into account the fact that the earth is not a perfect sphere. A great program to integrate into e-business solutions, dating sites, or just as it is as a service to your visitors.

- The Fluid Flow Calculator
This calculator is used to calculate pipe friction losses for straight piping handling water and water with varying percentages of ethylene glycol. The calculator uses an algorithm developed from the basic principles of fluid mechanics. This calculator allows the user to input the fluid type, the fluid temperature, the flow rate, the pipe size, pipe length, and pipe material. The calculator then determines the velocity, the Reynolds number, the Moody friction factor, the pipe friction factor, the pipe head loss, and the pipe friction loss in PSI.
