In reaction
turbine
Kinetic energy is appreciable as the fluid
The vanes are
partly filled
Total energy of fluid is converted to kinetic energy in the runner
It is not
exposed to atmosphere
It is not
exposed to atmosphere
Reaction turbine
is not exposed to atmosphere, only a part of the total head available at the
inlet to the turbine is converted to velocity head, before the runner is
reached.
Hence, the correct option is (D).
