Descrição

Studies the hydraulic equilibrium of a filtering variable declining rate system.

Given: Total flow, laminar flow coefficient (clean filter), turbulent flow coefficient, weir exponent and coefficient, filtering ares of each filter, maximum allowed head loss; calculates: flow in each filter, when all of them are working and one of them is out for washing, minimum and maximum head losses and the laminar coefficient in each filter of the system in their different colmatation stages.

Available options:

Filters minimum number: 3
Filters maximum number: 6
