    2018-11-28 · In any fan system, the resistance to air flow (pressure) increases when the flow of air is increased. As mentioned before, it varies as the square of the flow. The pressure required by a system over a range of flows can be determined and a 'system performance curve' can be developed (shown as SC) (see Figure 5.7).
