The total Tangential force on one ring of a Parson's Reaction turbine is 12000 N, when the blade speed is 100 m/s. The mass flow rate is 8 kg/s. The blade outlet angle is 20 degree. If the frictional losses occurred with pure impulse is 25 % of K. E. Correspondence to relative velocity at entry of each ring of blade. The expansion losses are 20% of heat drop in the blade. What will be the absolute velocity of steam at exit?
