WebAsk an expert. Question: At one stage of a reaction turbine the velocity of the steam leaving the fixed blades is 400 m/s and the exit angle is 22°. The mean blade speed is 200 m/s and the steam consumption is 100 kg/min. Assume the fixed and moving blades to be of identical section. (a) Sketch the blade inlet and outlet velocity diagrams. Web• The velocity diagrams for the moving blades of a 50% reaction turbine are shown in Fig. 7.31. • With a simple impulse type the value of Vr2 (= kb Vr1 ) would be given by BE, but in the reaction turbine this velocity is increased to BC by further expansion of the steam in the nozzle-shape blade channels.
