If the difference between the axial components of velocity at the inlet and outlet of a de-Laval turbine is 120 m/s and the mass flow rate of steam is 7 kg/s, then the axial thrust on the rotor is:

In a reaction turbine stage, the enthalpy drop in the stator (fixed) blades is 4.62 kJ/kg and that in the rotor (moving) blades is 2.38 kJ/kg. The degree of reaction of the stage is:

The data for an impulse steam turbine is given as follows: (i) Mean blade velocity = 400 m/s (ii) Absolute velocity of steam at the inlet to the moving blade = 1200 m/s (iii) Sum of velocities of whirl at the inlet and the outlet of the blade = 1500 m/s What will be the efficiency of the blade?
