odynamic Machinery 11.9 In the blade group of Problem 11.8 there are five pairs of blades. Calculate the useful enthalpy drop required for the group and the diagram power. (117.8 kJ/kg; 553.7 kW)
11.8. The speed of rotation of a blade group of a reaction turbine is 3000 rev/min. The mean blade velocity is 100 m/s. The blade speed ratio is 0.56 and the exit angle of the blades is 20°. If the mean specific volume of the steam is 0.65 m?/kg, and the mean height of the blades is 25 mm, calculate the mass flow of steam through the turbine. Neglect the effect of blade thickness on the annulus area, and assume 50% reaction blading.
