A non-ideal regenerative Rankine cycle for a power plant (shown below), where there is no heat loss or pressure drops in the piping, the turbine and pumps are "not" isentropic (q-out(turbine)=0.09 q-in(boiler), q-out(I)=0.02 q-in(boiler), & q-out(II)=0.03 q-in(boiler)), the heat loss in open feedwater heater (FWH) can be neglected, there are no pressure drops in the boiler, condenser, and FWH, and the steam leaves the condenser and FWH as saturated liquid.
a)sketch the T vs. s cycle/diagram for this ideal Rankine power plant (including the T vs. s bell-curve for water/steam and the exact values of P & v at each stage).
b)sketch the P vs. v cycle/diagram for this ideal Rankine power plant (including the P vs. v bell-curve for water/steam and the exact values of P & v at each stage).
c)what is Mass flow rate at stages 6 & 7?
d)how much heat input (to the boiler) is needed in 5 seconds?
e)what is the net rate of work output
state1: sat-liquid at 10kPa out of condeser into Pump1
state 2 sat liquid at 1.2Mpa out of Pump 1 into Open FWH
state 3: sat-liquid at 1.2MPa out of Open FWH into Pump 2
state 4: sat-liquid 15Mpa out of Pump 2 into boiler
state 5: Mass flow rate of 15kg/s, gas at 15MPa at 600 degrees Celsius out of Boiler into Turbine
state 6: Gas at 1.2MPa out of Turbine into Open FWH
state 7: gas at 10kPa out of Turbine into Condenser
at Pump2 you have q-out(II)
at Boiler you have q-in(boiler)
at Turbine you have q-out(turbine)
at Condenser you have q-out
at Pump 1 you have q-out(I)
