Nozzle Velocity vs. Bailing Velocity

The V-Cone. To determine the actual air volume (CFM) being produced, a flow meter such as a V-Cone from McCrometer can be very useful. The V-Cone conditions the air flowing through the string, and creates laminar flow (straight flowing air). It measures the pressure above the cone, then again below the cone, and converts the difference in pressure to a velocity measurement, which is later used to calculate the volume.The inside of the “V-Cone” flow meter by McCrometer.
