Figures

Grahic Jump Location
The relative uncertainty in the measurements of 〈U〉 as a function of Re
Grahic Jump Location
Normalized mean velocity distribution along the centerline of the jet. The solid line represents the potential flow velocity distribution. The accuracy of the measured velocity is estimated to be within ±1%.
Grahic Jump Location
Distribution of discharge coefficient CD as a function of Re in jets with two different nozzle configurations: [w,tN/w,BN/w] [12.7 mm, 1, 21.7] and [25.4 mm, 0.5, 10.8]. Note that two different working liquids were used for the jet with w=12.7 mm. See Fig. 2 for the corresponding estimates of uncertainty in CD. The solid line represents the potential flow solution for CD.
Grahic Jump Location
Schematic representation of the influence of Re on the trajectory of the separating streamline. The curve 1–2 represents the path of integration normal to the streamline.
