Steam at 200 bar, 760°C enters the throttle of a reheater engine and expands to 10 bar. At this point it leaves the engine, enters the reheater, and returns at 9 bar, 600°C, expansion then occurs to the condenser pressure of 0.5 bar (hf = 138 kJ/kg) on the basis of flow of 1 kg steam. Find (a) W and e of the cycle, (b) W, e, and m for the ideal engine, (c) In the actual engine the steam enters the reheater at 10 bar, 300°C and later expands to a saturated state at the exhaust to the condenser, find W, e and m.

Question
Steam at 200 bar, 760°C enters the throttle of a reheater engine and expands to 10 bar. At this point it
leaves the engine, enters the reheater, and returns at 9 bar, 600°C, expansion then occurs to the condenser
pressure of 0.5 bar (hf = 138 kJ/kg) on the basis of flow of 1 kg steam. Find (a) W and e of the cycle, (b) W, e,
and m for the ideal engine, (c) In the actual engine the steam enters the reheater at 10 bar, 300°C and later
expands to a saturated state at the exhaust to the condenser, find W, e and m.
