Input data

Flow (Q)

Superficial area (A)

Washing velocity (Ua)

Number of filters (n)

Output data

Washing flow (QL)

Inlet area to the filters (AI)

Outlet area of the filters (Ao)

Area for washing water(Apl)

Area of washing water(AL)

Description

Given the flow to be filtered $Q$ , the number of filters $n$ , the superficial area $(A = a \cdot b)$ of each filter and the washing velocity $U_a$ , calculates the minimum reccomended areas for inlets and outlets to the filters.

Filter

Observation

The washing velocity must be between 0.60 and 0.95 m/min.
