Tubi PVC - PN 6 : Ottimizza i tuoi impianti idraulici | calcola le perdite di carico!

Scopri come dimensionare correttamente i tuoi impianti idraulici in PVC con la nostra tabella completa di perdite di carico!

In questa pagina trovi tutti i dati necessari per calcolare le perdite di carico nei tubi in PVC con pressione PN 6 e diametri compresi tra 50 e 280 mm. I valori, ottenuti dalla formula di Hazen-Williams, ti permettono di:

Progettare impianti idraulici efficienti.

Stimare le prestazioni dei sistemi di trasporto fluidi.

Ridurre i consumi energetici.

Nella tabella trovi:

Diametro nominale del tubo (DN).

Portata (Q) in litri al secondo (l/s).

Velocità media del flusso (V) in metri al secondo (m/s).

Perdita di carico (J) in metri per chilometro (m/km).

Come utilizzarla:

Scegli il diametro del tuo tubo (DN) nella prima colonna.

Individua la portata (Q) nella prima riga.

Interpola per trovare la perdita di carico (J) all'incrocio tra riga e colonna.
