In the present paper, the experimental data are shown with respects to the pressure and velocity distribution in the whirl pool chamber at different running states of a centrifugal blower. From these, some interesting phenomena which differ from what was expected when it was designed, became clear. Above all, the following is remarkable. Static pressure is hardly recovered in the neighbourhood of inlet, where the boundary layers along the both walls of chamber grow quickly as radius increases and their displacemental effect cancells the radial enlargement of area proportional to radius, and begins to increase uniformly after the flow passes through the inlet region. The efficiency of recovery of static pressure seems to be almost determined by the length of inlet region.
