. The direction of flowmay be either outward or imvard;that is, the turbine may have in-icrnal or external feed (Figs. GOand G7). An axial- or parallel-flow turbine is one in which (he dis-timce of a particle from the axis of rotation remains constant duringits passage through the wheel (Fig. 68).… … 05.
