In axisymmetrically opposed jets, it has been asserted that the location of the impinging surface was determined mainly by two opposed-nozzle exit momentums. It was shown in the 1st report that pressure fluctuations on the axis of the opposed jets play an important part in determining the location of the impinging surface. In the present paper, in an opposed jet flow, the mechanism to determine the location of the impinging surface is elucidated by experimental results of the usual turbulent impinging jet on a plate, instead of the impinging surface. In the flow between the nozzle and the impinging plate, mean velocity distributions and total pressure distributions, it is ascertained that kinetic energy transportation is influenced very much by the existence of a body, for instance, a slender bar, on the axis of the impinging jet.
