Question
The following data relate to a compound
impulse turbine having two rows of
moving blades and one row of fixed blades
in between them. Steam velocity coming
out of nozzle= 450 m/sec., Nozzle angle
%3D
15°, Moving blades tip discharge angles
%3D
30°, Fixed blade discharge angle = 20°,
6.
Friction loss in each blade rows = 10% of
%3D
the relative velocity. Find the blade
velocity, blade efficiency and specific
steam consumption for turbine.
