Question

In a reheat cycle steam at 15 Mpa, 540°C enters the engine and expands to 1.95 Mpa. At this point the
steam is withdrawn and passed through a reheater. It reenters the engine at 540°C. Expansion now occurs
to the condenser pressure of 0.0035 Mpa. (a) For the ideal cycle, find ee (b) A 60,000 kW turbine operates
between the same state points except that the steam enters the reheater at 1.95Mpa and 260°C, departs at
1.8 Mpa and 540°C. The steam flow is 147,000 kg/hr; generator efficiency is 96%. For actual engine, ek, mk,
and nk, (c) Determine the approximate enthalpy of the exhaust steam if the heat lost through the turbine
casing is 2% of the combined work.
4. Steam at 200 bar, 760°C enters the thrott
