At a stage in a reaction turbine, the mean blade ring diameter is 1 m and the turbine runs at a speed of (50+ last digit of your roll number) rev/sec. The blades are designed for 50% reaction with exit angles 30^o , and inlet angles 50^o . The turbine is supplied with steam at the rate of 6,00,000 kg/hr and stage efficiency is 85%. Determine 

(i) the power output of the stage.

 (ii) the specific enthalpy drop in the stage in kJ/kg. 

(iii) the percentage increase in relative velocity in the moving blades due to expansion in these blades.
