Calculating Pipe Flow Performance

Flow performance is of the utmost importance in piping system design; an optimal design will reduce capital, installation, and operating costs. This flow calculator allows the user to easily determine critical flow properties (flow rate, velocity, and friction loss) of thermoplastic piping systems, and facilitates a rapid comparison between alternate pipe materials.

Additionally, the calculator can be used to determine approximate energy costs associated with the specified amounts of water being delivered (Energy calculations based on electrical rates provided by the Department of Energy).

Default values have been provided for many of the parameters used in the calculator, please feel free to adjust these parameters to your specific requirements.
