= (#3pp5dimagiba) A turbine with one extraction for regenerative feedwater heating, receives steam with an enthalpy of 3373 kJ/kg and discharges it with an exhaust enthalpy of 2326 kJ/kg. The ideal regenerative feedwater heater receives 11,338 kg/hr of extracted steam at 345 kPaa (whose h = 2745 kJ/kg). The feedwater enters the heater with an enthalpy of 140 kJ/kg and departs saturated at 345 kPaa. Calculate the turbine power. Π 1 Wk turbine gen. I₁ Boiler cond. 4 pump heater hot well 4 pump

T B A D Consider the cycle in the diagram (very similar to the Rankine Cycle) using water as the working fluid. Process A-B: A saturated mixture of water is pumped from low pressure to a high pressure saturated liquid in an iso- entropic (and adiabatic) process. Process B-C: The high pressure saturated liquid enters a boiler where it is heated at constant pressure process by an external heat source to a super-heated vapor. Process C-D: The super-heated vapor goes through a turbine, generating power exiting as a saturated vapor. Assume an iso-entropic (and adiabatic) process and neglect kinetic energy and potential energy changes. Process D-A: The saturated vapor then enters a condenser where it is condensed at a constant pressure process back to its original state. The boiler operates at 8 MPa (points B & C) and the condenser operates at 200 kPa (points A & D). Assume a mass flow rate of 1 kg/s. Make a table of the temperature, pressure, volume, internal energy, enthalpy, entropy and…
