The degree of
reaction for Parson's reaction turbine is ________ .
0
0.75
0.5
0.25
0.5
Degree of reaction is defined as the ratio of the static enthalpy drop in the rotor to the static enthalpy drop in the stage.
In Parson’s
reaction turbine, pressure drop is equally shared by the stator and the rotor.
Thus, R = 0.5
for Parson’s reaction turbine.
Hence, the
correct option is (C).
