A pressure compounding impulse turbine consist of four stages is designed for power production. The steam enters the turbine at 1.0 bar and 200 °C. The exit pressure of the steam from the turbine is 0.3 bar. The enthalpy drop is same in all stages. The overall isentropic efficiency is 0.83 and the nozzle angle is 20° to the rotor. The exit angle of the rotor blade is 23°. The blade velocity is 336 m/s and blade velocity coefficient is 0.95. The mass flow rate of the steam is 15 kg/s and the mean diameter of the rotor is 1.2 m. The work produce and blade angles of all stages are same. • Sketch neat and clean actual and ideal expansion process on Mollier diagram (h-s Chart). • Draw velocity triangle and calculate the following parameters. a) Rotor inlet pressure of each stage b) Total Work done and power developed c) Blade height of each rotor blade d) Axial thrust e) Reheat factor
