A regenerative steam power cycle with an open regenerator is used to produce a net power of 330 MW. The steam enters the first expansion stage at 12 MPa, 560°C and expands to 1 MPa, where part of the steam is extracted for regeneration. The rest of the steam continues to expand to 6 kPa. The feed water leaves the regenerator as a saturated liquid at 1 MPa. If the turbines and pumps are isentropic, calculate the following: (a) The thermal efficiency of the cycle. (b) The mass flow through the first stage of the turbine. Se utiliza un ciclo de potencia de vapor regenerativo con un regenerador abiertopara producir una potencia neta de 330 MW.
