An axial flow pump handling oil of specific gravity
0.8 at a rate of 1.0m3 s-1 is fitted with downstream guide
vanes and its impeller rotates at 250 rev min-1. The oil
approaches the impeller axially, and the velocity of flow,
which may be assumed constant from the hub to the tip, is
3.0ms-1. The pump consumes 60 kW, the overall efficiency
being 77 per cent and the hydraulic efficiency (including
guide vanes) is 86 per cent. If the impeller diameter is 0.8m
and the hub diameter is 0.4 m find the inlet and outlet blade
angles and the guide vane inlet angles at the hub and at the
tip. Assume that the total head generated at the hub and at
the tip is the same.
