Output data

Washing flow

Description

Given the superficial area of the filter and the desired ascending velocity, the filter washing flow is calculated.

Formula

Vl=A⋅UaV_l = A \cdot U_a

Where:

  • VlV_l = washing flow (m³/s)\text{(m³/s)}
  • AA = superficial area of the filter (m²)\text{(m²)}
  • UaU_a = washing velocity (m/min)\text{(m/min)}
