Q5. In a 50 % reaction turbine stage, the steam leaves the fixed blades with a velocity of 500 m/s. The mean diameter of the blade ring is 900 mm and the speed of rotation is 8000 rev/min.

The inlet angle of the blading is 70°. Calculate EACH of the following:

(a) The blading outlet angle; (4)

(b) The blade work per kg of steam flow; (4)

(c) The enthalpy drops across the moving blade; (4)

(d) The diagram efficiency. (4)
