The following particulars apply to a two-row velocity compounded impulse stage of a turbine: nozzle angle 17; blade speed 125 m/s: exit angles of the first row moving blades, the fixed blades, and the second row moving blades, 22, 26, and 30" respectively. Take the blade velocity coefficient for each row of blades as 0.9, and assume that the absolute velocity of the steam leaving the stage is in the axial direction. Draw the velocity diagram for the stage and obtain: (i) the absolute velocity of the steam leaving the stage; (ii) the diagram efficiency. 1722 m/s; 80%)

Question
The following particulars apply to a two-row velocity compounded impulse stage of a
turbine: nozzle angle 17; blade speed 125 m/s; exit angles of the first row moving blades,
the fixed blades, and the second row moving blades, 22, 26, and 30° respectively. Take
the blade velocity coefficient for each row of blades as 0.9, and assume that the absolute
velocity of the steam leaving the stage is in the axial direction. Draw the velocity diagram
for the stage and obtain:
(i) the absolute velocity of the stearm leaving the stage;
(ii) the diagram efficiency.
