Tables and curves are presented which give values of the induced-upwash-velocity factors, due to the jet boundary, at the horizontal center plane of a closed circular wind tunnel and at that of a closed bipolar wind tunnel which is formed when a reflection plane is installed in a circular tunnel for testing semispan wings. These velocities have been calculated for infinitesimal-span lifting elements located at various points in the horizontal center plane.
