In this experiment, the salt water issued into a basin filled with freshwater at various condition. Results of this experiment are also compared with the free buoyant jet theory. The following results were obtained : ( 1 ) The trajectory of buoyant jet agreed well with one of the free buoyant jet theory from nozzle to bottom. ( 2 ) Collision with the bottom promoted the entrainment of the buoyant jet issuing into a basin.
