Steam at 29.4 N/cm2 absolute and dry saturated comes out of rotor of a reaction turbine having identical bladings. The velocity of steam entering into the turbine is 100 m/s. The mean blade height is 4 cm and the exit angle of the moving blade is 20. The blade velocity is 4/3 times of axial flow velocity at the mean radius. If the steam flow rate is 2.5 kg/s. Find (i) the rotor speed, (ii) h.p. developed, (iii) the diagram efficiency, (iv) the percentage increase in relative velocity in the moving blades, and (v) the enthalpy drop of steam in blade passage.
