HM 220 Airflow Study Unit

The illustration shows the velocity profile in the open jet that is measured using the Pitot tube at the fan outlet. Here the dimension x is the distance between the measuring opening and the outlet. The lateral separation of the measuring opening from the centre of the fan outlet is plotted on the y-axis in mm. The velocity of the air flow in m/s is plotted on the x-axis in m/s. Velocity profile
