This web site is offering pipe flow calculators for everyday problem solving in the field of fluid dynamics. Many desktop and online server side calculators, as well as three calculators for Android smartphone, are available now.

This web site offers a simplified resolution of less and medium complex fluid mechanics problems, primarily in the part of fluid motion and fluid dynamics.

A large number of calculators solved practical examples, theoretical explanation with corresponding equations allow finding a correct approach to solving practical problems, which we meet in every day practical work.

I am Mechanical engineer for hydropneumatic technique, with more than 15 years of engineering experience in the field of pipeline and piping design and construction, metering and regulating of gaseous and liquid hydrocarbons, water and air.

The first calculator – Venturi tube calculator was created and published on the Aug 1st, 2000 on a free domain (flow.netfirms.com), which is no longer active. Since then, additional calculators – Java applets for desktop computers were created as well as 3 calculators for Android devices and several calculators that work on the server side. In addition, I have created and published a significant number of texts that are showing a theoretical background of applied fluid mechanics in calculators.

Further development of new and improvement of existing calculators, as well as new content adding, are part of the vision that this web site will become and stay default place where practical problems in the field of fluid mechanics will be solved on the simple and correct way, on a daily basis.

After the project has started in the year 2000, instantly it was a success and appreciated by a number of professionals, professors, and students. Positive comments and my commitment to Java and programming, in general, pushed the development that later followed.

During the past 20 years, I have redesigned the web site multiple times. In addition, the calculator evolved on its own from AWT to SWING, from Java applet to web start application and to native Windows application. In the meantime, I have developed also a server-side version of the calculators and all is now available under one single domain name – pipeflowcalculations.com.

In the early days, calculators were available only as online Java applets, served from the free hosting account on the flow.netfirms.com. Later, once the advertising program with GlobalSpec and AdSense started, I moved the web site to the paid servers with a dedicated domain name. The first domain was fludy.com, and later I registered pipflowcalculations.com.

In August 2016, when calculators started to be available for download as a Web Start Java application, I have introduced the paid subscription. Nowadays, a number of subscribed users is rising every day, I am assured that you, as my valued customers, are appreciating my work and my passion for engineering calculations and computer programming and that you are recognizing my dedication to this project.
