Flow characteristic curve

WebLooking at the pump / system curve (Figure 1) you can see the intersection occurs at a flow rate of 400 gpm resulting in a total pump head of 70 ft. As a result, the balanced flow rate through the system occurs at 400 gpm. Figure 1. Controlling Flow with a Control Valve Webdistorts the flow characteristics curve. When the damper begins to open, the differential pressure is high, and the flow increases at a higher rate than what the inherent curve suggests. When the damper is almost fully open, the pressure drop across the damper will be small, Damper Applications Guide 1 4 ®
