![2. (#6-DimagPP18) A reheat regenerative steam cycle operates with condenser pressure of 0.007 MPa.
Steam at 13.5 MPa and 540 C leaves the steam generator and enters the turbine at 13 MPa and 540 C.
Expansion takes place in the turbine to a pressure of 3.45 MPa and a temperature of 350 C. At this
condition, the steam is re-heated at constant pressure to a temperature of 480 C. The reheated steam
expands to 0.70 MPa and 260 C where a portion of steam is extracted to an open feedwater heater. The
remaining steam continues to expand to an exhaust pressure of 0.007 MPa and a quality of 88 %.
Neglecting the effect of pump work, determine:
a) QA
b) Work of the turbine
c) The thermal efficiency of the engine](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd735a397-8353-4b82-b258-80b9a49f74ef%2F835134d2-cad7-41b2-a356-a05a5838a536%2Fqrrsgqi_processed.png&w=3840&q=75)
