The nozzles of a two-row velocity-compounded stage have outlet angles of 22 degrees and utilize an isentropic enthalpy drop of 200 kJ per kg of steam. All moving and guide blades are symmetrical, and the mean blade speed is 150 m/s. Assuming an isentropic efficiency for the nozzles of 90 per cent, find graphically all the blade angles and calculate the specific power output produced by the stage. The velocity at inlet to the stage can be neglected.
