Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. The isentropic efficiency of the turbine is 76 percent and that of the pump is 95 percent.
A: Determine the quality (or temperature, if superheated) of the steam at the turbine exit.
B: The thermal efficiency of the cycle.
C: The mass flow rate of the steam

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,...

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...

enters the turbine at 9 MPa and 575 ° C and exits at 150 ° C, then
it is cooled in the condenser to a pressure of 100 kPa by means of
the cooling water from a lake and that circulates through the
condenser tubes to a rate of 1370 kg / s. Consider leaving the pump...
