A single row impulse turbine develops 2.3 MW at a blade speed of 105 m using 52 kg of steam per second. The velocity of steam leaving the nozzle at 310 m/s. Determine the angles of nozzle and blade when the steam leaves the turbine blades at a half angle of axial direction flow while the exit whirl velocity is one-third the total whirl velocity. When a second moving and stationary rows of turbine are connected to the above single moving row with the same angles except the steam leaves the second row axially, find the specific steam consumption. (solve using the velocity diagrams)
