The Hysopt software supports 3 methods for pipe sizing:
- Maximum velocity
- Maximum pressure drop per square meter
- Target pressure drop per square meter
In default, Hysopt does a pipe selection based on the BBRI (Belgian Building Research Institute) standard report number 14. The standard is based on the maximum velocity method and is typically used for pipes inside a building (relatively low velocities are allowed because of noise pollution).
The user can change the pipe sizing method by first clicking on the button in the top right corner of the screen stating "model settings".
A popup window will appear where the user can change different design options including the pipe types and pressure profiles. The user can change everything by exporting the excel sheets, changing them, and importing them again. The user can export the pipe types and pressure profile by clicking on the white cloud buttons and import them by clicking on the blue cloud buttons.
This way, any standard for pipe selection and/or pipe physical properties can be implemented and applied in our software.
How can I modify the pressure profiles for pipes during pipe selection?

Summerized : when both are supplied the most restrictive is applied. A "0" value is ignored.
Cibse guide CP1 for pipe sizing (external pipe network)
The Cibse guide CP1 is often used (in the UK) for sizing pipes in external pipe networks (e.g. district heating).
At this moment our software only supports pipe sizing based on the maximum velocity, the maximum pressure drop per square meter, and the target pressure drop per square meter. However, in the Cibse guide, the pipe sizing is done on typical (or target) velocity.
To still be able to size pipes based on the Cibse guide, excel sheets are created which design pipes based on the max velocity method, but with almost the exact same results as the typical velocity calculation presented in the Cibse guide.
The excels are thoroughly tested and can be implemented in our software:
