In a De Laval turbine steam issues from the nozzle with a velocity of 1200 m/s. The nozzle
angle is 200
, the mean blade velocity is 400 m/s, and the inlet and outlet angles of blade are
equal. The mass of steam flowing through the turbine per hour is 100 Kg. Calculate: i) Blade
angles. ii) Relative velocity of steam at inlet. iii) Power developed. iv) Blade efficiency. Take
blade velocity coefficient as 0.8.
