The characteristics of the air jets issuing from two kinds of exit shapes with an aspect ratio of 5 were measured at the first half of the experiment. Discrepancies between the orifice-type jet and the nozzle-type jet with a parallel part are clarified for two bilaterally symmetric planes of the jets. At the latter half of the experiment, submerged jets, colored by blue-black ink, are issued into a water tank and observed for exits of different exit shapes and aspect ratios. The observed flow types corresponded to the already known characteristics of the jet spread in the two bilatellary symmetric planes. In addition, it is interesting to find that the relative magnitude of the spread in the planes changed twice. This is also the case for both the nozzle- and orifice -type jets with a small exit velocity (a low Reynolds number).
