Question
1. A regenerative Rankine cycle operates with one closed feedwater heater. The condensate from
the heater passer through a steam trap and enters the condenser. The turbine inlet steam
conditions are 10
+ 9
MPa, 550 + 9
1°C, and 50 + 9
.) kPa,
`kg/s. The steam expands isentropically to 750 + 9
where extraction occurs for feedwater heating. The remaining steam expands to 7.5 + 9
kPa. Determine (a) the cycle thermal efficiency; (b) the mass flow rate of steam; (c)
the net power produced.
Draw both T-S diagram and component diagram as describe in the problem.
