Open Area Ratio
It is the ratio of the open area through the strainer basket to the cross sectional area of the pipeline. A well designed basket strainer should have an open ratio of at least 4 to 1. Anything less may cause excessive pressure drop. The ratio is calculated with a clean basket and as the basket begins to clog the ratio will drop. Unless there is a wide safety margin the area through the basket may quickly become smaller than the pipe area. This will reduce flow through the strainer and necessitate very frequent cleaning. A small open area ratio also means the holding capacity of the basket is small - an important consideration if the amount of solid matter to be removed is large.

rapporto tra superficie libera e superficie totale
Sideve evitare l'intasamento che provoca una diminuzione di portata e una caduta di pressione.
Con libera intendo "non intasata/ostruita"
Quando dice che ci vuole un rapporto di 4 a 1 penso che si intenda che almeno 4/5 debbano essere liberi e 1/5 intasato
Con libera intendo "non intasata/ostruita"
Quando dice che ci vuole un rapporto di 4 a 1 penso che si intenda che almeno 4/5 debbano essere liberi e 1/5 intasato
