Download pipe flow calculators
At this moment it is not possible to download any of the available calculators that you have already used on this site(read terms of service).
Also selling is not a option at this moment. Instead of selling calculators, I have decided to offer this service free of any charge, through Java applets that anyone with Internet connection can use. In this way you always use the most recent version of calculator.
As thousands of users are every day using calculators, eventual bugs are instantly reported and immediately fixed.
Enjoy to use this free service, and if you have any comments feel free to contact me.
