Description

Given the flow to be filtered QQ, the number of filters nn, the superficial area (A=a⋅b)(A = a \cdot b) of each filter and the washing velocity UaU_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.
