Design considerations

The design of a piping network based on RENOVATION VRC and RENOVATION VRC BLUE is focused on the determination of the pipe diameter for a specific lay-out once parameters as flow, total length, piezometric height and roughness are completely defined.
The criteria for dimensioning a pipeline, as described in standards, must be able to fulfill the maximum required flow, balancing the water supply according to the demand and evaluating the velocity of the fluid in the pipe, the roughness coefficient of the internal surface and the pressure difference between the ends of the piping system.
The distributed pressure drop may be estimated through an abacus which links the flow (Q) and the velocity (V) of the fluid to the internal diameter (d) of the pipeline. It is generally advisable to operate with a fluid velocity in the range 0.5-2.5 m/s in order to avoid overpressure and stagnation. On the other hand, the pressure drops due to the flow through fittings and valves have to be estimated according to their specific type as described in standards.
Pipelines based on RENOVATION VRC and RENOVATION VRC BLUE are also suitable for fire-fighting networks provided national rules are taken into account for this specific use.
