Steam issues from the nozzle of a De-level turbine at
a velocity of 1000 m/s at an angle of 20ᵒ. The
blade velocity is 300 m/s and blades are symmetrical. The mass flow
rate is 0.5 kg/s and a friction
factor is 0.8. With the help of velocity diagram, determine 1)
Blade efficiency 2) Power developed 3)
Stage efficiency if the nozzle efficiency is 95%
