4. An ideal double reheat steam turbine receives 300,000 kg/h of steam at 10 MPa and 400°C. After expansion from high pressure shell, it is reheated twice from saturated vapor condition back to its initial temperature. The steam entering the condenser is 97% dry. Determine: (A) Engine work (B) Engine thermal efficiency

Determine: (A) Engine work (B) Engine thermal efficiency
(A) W =
1558.5 kJ
(B) e. = 40-12%
These should be the final answer
