Understanding Fluid Flow Rate (Q) for Efficient Water Supply

Determining the FLOW RATE (Q)
The quantity of fluid that passes through a section of area “A” in unit time. The first value to calculate when sizing a pressurisation unit is the total quantity of water it must supply to satisfy the maximum theoretical demand, given by the sum of the water demand at each point of delivery.
The table gives the values of maximum simultaneity of water flows per number of apartments with 1 or 2 WC’s (with cistern or direct flush).
