This paper concerns with the experimental results of the outward and inward flows in radial-flow nozzles. With an air source of 500 mmAq gauge pressure, the overall pressure losses and pressure distributions are obtained for various flow rates. It follows that the results of the theoretical analysis obtained in the 1st and 2nd reports are applicable to the practical problems with reasonable accuracy in spite of simple assumptions. However, when flow is outward and the inner corner of a nozzle is sharp, a severe contraction will occur and experimental results will not be consistent with theoretical values. Since the clearances of the nozzles dealt with are extremely narrow, the velocity distribution in the clearance cannot be obtained by the experiment.
