WebWhen a fan is used to move air through electronic equipment, the flow through the systems is determined by the intersection of the performance curve and the resistance curve. At this point of operation, the pressure available from the fan to force air through the system is equal to the pressure required by the system for that flow. WebChris explains what a system curve is and why is it helpful. Topics covered include friction loss, selecting pipe/fittings, flow, head, and how system curve...

WebThe fan volume flow rate (airflow) is commonly expressed in cubic feet per minute, or CFM. Therefore, the system pressure loss and volume flow rate requirements are typically expressed as a certain value of static pressure (SP) at some CFM. The fan “pressure-volume” curve is generated by connecting the fan to a laboratory test chamber. WebThe actual curve crosses the capacity line in A.
