Mechanical Engineering

Superheated steam at 8 MPa and 480°C leaves the steam generatorof a vapor power plant. Heat transfer and frictional effects in theline connecting the steam generator and the turbine reduce thepressure and temperature at the turbine inlet to 7.7 MPa and 440°C,respectively. The pressure at the exit of the turbine is 10 kPa,and the turbine operates adiabatically. Liquid leaves the condenserat 8 kPa, 36°C. The pressure is increased to 8.6 MPa across thepump. The turbine and pump isentropic efficiencies are 88%. Themass flow rate of steam is 79.53 kg/s. Determine

(a) the net power output, in kW.
(b) the thermal efficiency.
(c) the rate of heat transfer from the lineconnecting the steam generator and the turbine, in kW.
(d) the mass flow rate of condenser cooling water,in kg/s, if the cooling water enters at 15°C and exits at 35°C withnegligible pressure change.
book used is fundimentails of thermodynamics
