In a stage of an impulse turbine provided with a single row wheel, the mean diameter of the blade ring is 80 cm and the speed of rotation is 3000 rpm. The steam issues from the nozzles with a velocity of 300 m/s and the nozzle angle is 20°. The rotor blades are equiangular and due to friction in the blade channels the relative velocity of steam at outlet from the blades is 0.86 times the relative velocity of steam entering the blades. What is the power developed in the blades when the axial thrust on the blades is 140 N

In a stage of an impulse turbine provided with a single row wheel, the mean diameter of blade ring is 0.08 m and the speed of rotation is 3000 rpm. The steam issues from the nozzle with a velocity of 300 m/s and the nozzle angle is 20 degree. The blades are equiangular and blade coefficient is 0.85. determine the.
