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 condense is 97% dry. Determine: (A) Engine work (B) Engine thermal efficiency (C) Steam rate
