This supplement treats the following items : 1) The effect of initial condition of the trapping flow on the pressure rise was dealt with, and the very small effect has been shown. 2) The change of pressure distribution along the relief groove was treated and shown (Fig. 6). 3) The effect of partition of the relief groove on the delivery has been treated. The results are : The relief groove has the same efffect on the delivery range and the suction range of trapping. If the thickness of partition wall is given, the symmetrical groove is effective, and the very thin wall is found most effective. If the relief groove on one side is fixed, the groove shows the corresponding effect depending upon the thickness of partition (Fig. 9). 4) When the cavitation occurs in the trapping flow, the relief groove is more effective for the shorter groove on suction side and the longer groove on delivery side (Fig. 14).
