When steam
flows over moving blades of an impulse turbine
Both pressure
and velocity decreases
Pressure
drops and velocity increases.
Pressure
remains constant and velocity decreases.
Both pressure
and velocity remains constant.
Pressure
remains constant and velocity decreases.
A
reaction turbine is one in which there is pressure and velocity loss
in the moving blades. The moving blades have a converging steam nozzle.
Hence when the steam passes over the fixed blades, it expands with
decrease in steam pressure and increase in kinetic energy.When steam
flows over moving blades of an impulse turbine, pressure remains constant and
velocity decreases.
Hence, the
correct option is (C).
