Upward Velocity Calculation:
To determine the upward velocity of the sedimentation tank the flow rate through the tank was divided be the cross sectional area of the tank. In order to make our model comparable to the sedimentation tanks that are built on a full scale the upward velocity needs to be the same. The upward velocity in Ojojona was found to be 100m/day. Thus this was the parameter we used for this model as well.
