Consider a regenerative Rankine cycle with one steam
extraction point using an
open feed-water heater (OFWH).
P at boiler = 5 MPa
T at turbine inlet = 600 0C
P at OFWH = 1 MPa
P at condenser = 10 kPa
All device efficiencies = 1
Solve the problem analytically step by step; find all work
interactions, heat transfers, and
the thermal efficiency.

A power plant operates on a regenerative vapor power cycle with
one open feedwater heater. Steam enters the first turbine stagge at
12 MPa, 560*C and expands to 1 MPa, where some of the steam is
extracted and diverted to the open feedwater heater operating at 1
MPa. The remaining steam expands through the second turbine stage
to the condenser pressure of 6 kPa. Saturated liquid exits the open
feedwater heater at 1 MPa. The net power output for the...

use your Steam Tables. Refer to the H2O properties given in the
table below.
A regenerative cycle with one stage of
reheating is executed with steam expanding initially from 20 Mpaa
and 540 deg C. The reheater pressure is 10 Mpaa. The steam leaves
the reheater at 540 deg C. Steam is bled after reheating to one
CFWH and on one OFWH a pressure equal to 5 Mpaa and...

Consider a steam power plant that operates on a regenerative
Rankine cycle and has a net power output of 150 MW. Steam enters
the turbine at 10 MPa and 500°C and the condenser at 10 kPa. The
isentropic efficiency of the turbine is 80 percent, and that of the
pumps is 95 percent. Steam is extracted from the turbine at 0.5 MPa
to heat the feedwater in an open feedwater heater. Water leaves the
feedwater heater as a saturated liquid....

Consider a Rankine cycle with an ideal intermediate steam
pickup, one of which is open and the other is closed feed water
heaters. The steam enters the turbine at 12.5 MPa pressure and 550
degrees Celsius temperature and expands to 10 kPa condenser
pressure. The steam separated from the turbine at 0.8 MPa pressure

A steam power plant operates on a regenerative Rankine cycle.
Steam enters the turbine at 6 MPa at 700 ºC and the condenser at 10
kPa. Turbine has isentropic efficiency of 85% and pumps have
isentropic efficiency of 90%. Steam is extracted from the turbine
at 0.6 MPa to heat the feedwater in an open feedwater heater. Water

A steam power plant operates on an ideal regenerative Rankine
cycle. Steam enters the turbine at 6 MPa and 450oC and is condensed
in the condenser at 20 kPa. Steam is extracted from the turbine at
0.4 MPa to heat the feedwater in an open feedwater heater. Water
leaves the feedwater heater as a saturated liquid. Show the cycle
on a T-s diagram and determine the fraction of steam extracted from
the turbine for the open feedwater heater.
