註釋
An experimental radial-discharge impeller was designed to have, by comparison with conventional impellers, a long radius of axial-plane curvature, a large axial depth, and a small inlet-blade root diameter. The impeller had conventional inlet-bucket bending and inlet and discharge diameters similar to an existing commercial impeller. This experimental impeller was tested as part of an investigation to improve the flow capacity of radial impellers. The performance effect of impeller passage area was investigated by tests of a series of three impeller front-shroud profiles. The impeller passages of profile 1 had constant area along the mean flow path taken in an axial plane. Profiles 2 and 3 had uniformly converging areas along the mean flow path.
