Ideal Reheat Steam Cycle (10)
Consider a steam power plant operating on the ideal reheat Rankine cycle. Steam enters the high-pressure turbine at PH MPa and TH °C and is condensed in the condenser at a pressure of PL kPa. Assume the steam is reheated to the inlet temperature of the high-pressure turbine, and that pump work is NOT negligible. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed w% percent, determine:
(a) the pressure at which the steam should be reheated and show how you got the quality,
(b) the total turbine work ,
(c) the net work ,
(d) the total heat input , and
(e) the thermal efficiency of the cycle .
PH = 20 MPa, TH = 700 °C, PL = 10 kPa and w% = 12.9%.

Consider a steam power plant operating on a simple ideal Rankine
cycle in which the steam enters the turbine at 3 MPa and 350C and
is condensed in the condenser at 75 kPa. Determine the thermal
efficiency of this cycle and sketch an appropriately labeled T-s
diagram. Also compare this thermal efficiency to that a Carnot heat
engine operating between these same two limits.

A proposed steam power plant design consists of an ideal Rankine
cycle with reheat and regeneration. Steam enters Turbine 1 at P1
and T1 at the rate of m1 and exits at P2. A fraction (y') of the
steam exiting Turbine 1 is diverted to an open feedwater heater
while the remainder is reheated to T3 before entering Turbine 2.
The condenser operates at P4. Saturated liquid exits the condenser
and is fed to Pump 1. The outlet of Pump...
