Caleffi Pipe Sizer 4+

The WATER AND AIR FLOW HEAD LOSS TABLES, initially available only in printed form, are now available as a mobile app. CALEFFI PIPE SIZER. This application allows for sizing and making calculations for pipes and conduits carrying water or air, respectively for hydraulic or aeraulic plants.
The application's database contains the most common types of piping, grouped according to materials, shapes and most widespread dimensions, and it is possible to set the preferential units of measurement for all physical parameters used.

For both types of fluids (water – even water-glycol mixtures – or air), the application allows for making calculations for various purposes:
Calculation of distributed head losses in existing or pre-selected pipes
Distributed head losses refer to sections of linear pipes. After selecting the type, size and length of the pipe to be calculated, and specifying necessary data such as the fluid's temperature and the rated flow, the application calculates the total head loss of the pipe section, the linear head loss and the speed of the fluid under the specified conditions.

Sizing of pipes
If the pipes need to be sized, this mode allows for calculating the optimal dimensions of the pipe based on the project parameters specified by the user.
In addition to the type and length of the pipe section to be sized, the fluid's temperature and the rated flow, it is possible to set the typical project parameters by choosing between linear head loss or fluid speed, or both, in order to size the pipe. Moreover, it is possible to enter a maximum limit value for these parameters. The application will then calculate the pipe dimensions that most closely match the specified project conditions.
In the case of aeraulic plants, the application allows for sizing conduits with either round or rectangular cross-section.

Calculation of localised head losses
Localised head losses refer to non-linear pipe sections, such as bends, bottlenecks, branches and similar features. By means of a dedicated graphic support, the application allows for choosing one or more types of localised head losses, and calculating both the individual values and the total sum.
