Hydraulic Data
Water flow is restricted by the open area of grate. For the ACO Wexel range, there is no further reduction of flow from the underlying bodies. The head of water creates pressure and is also part of the calculation.
The table below shows the flow rate based on the diagram shown right.
Note that fixed or removable strainers will reduce the flow rates.
