STEAM WITH ABSOLUTE VELOCITY 300 M/S ENTERS THE STAGE OF AN IMPULSE TURBINE PROVÍDED WITH A SINGLE ROW WHEEL. THE NOZZLES ARE INCLINED AT 20° TO THE PLANE OF WHEEL AND THE ROTOR BLADES ARE EQUIANGULAR. THE ROTOR WITH MEAN DIAMETER 100 CM ROTATES WÍTH SPEED OF 8000 R.P.M. ESTIMATE THE POWER DEVELOPED IN THE BLADE IF THE AXIAL THRUST IN THE BLADES IS 145 N. IT MAY BE ASSUMED THAT DUE TO FRICTION IN THE BLADE PASSAGES THE KINETIC ENERGY DUE TO OUTGOING RELATIVE VELOCITY IS ONLY 67% OF THE KINETIC ENERGY DUE TO INCOMING RELATIVE VELOCITY.

Transcribed Image Text:STEAM WITH ABSOLUTE VELOCITY 300 M/S ENTERS THE
STAGE OF AN IMPULSE TURBINE PROVIDED WITH A
SINGLE ROW WHEEL. THE NOZZLES ARE INCLINED AT 20°
TO THE PLANE OF WHEEL AND THE ROTOR BLADES ARE
EQUIANGULAR. THE ROTOR WITH MEAN DIAMETER 100
CM ROTATES WITH SPEED OF 3000 R.P.M. ESTIMATE THE
POWER DEVELOPED IN THE BLADE IF THE AXIAL THRUST
IN THE BLADES IS 145 N. IT MAY BE ASSUMED THAT DUE
TO FRICTION IN THE BLADE PASSAGES THE KINETIC
ENERGY DUE TO OUTGOING RELATIVE VELOCITY IS ONLY
67% OF THE KINETIC ENERGY DUE TO INCOMING
RELATIVE VELOCITY.
