Hello, I need help with the following thermodynamics problem.Thank you! The compined cycle plant shown in figure uses a gas turbine engine operating with 250 kg/s of air entering at 300K and pressure ratio of 12.5.Use an idea air-starndard cycle as a model of this engine and assume the turbine inlet temperature is 1400K. The steam cycle operates in a simple rankine cycle between 10MPa and 70kPa.
1. Consider the following schematic of a power plant (operating in what is called a 'Rankine Cycle') Turbine Steam generator Condenser Coling water Economiaer The power plant control room reports that the plant is operating continuously at the following peak load conditions: a. Power to pump = 300KW b. Rate of steam flow = 25 kg/s c. Cooling water temperature at condenser inlet = 13 C d. Cooling water temperature at condenser outlet = 34 C Additionally, the following measurements were made at various points in the piping connecting the power plant components Data Pressure Temp.

i need some one explian the TS digram Rankine Cycle please don't use google
I need the answer as soon as possible
This problem is about "An Ideal Rankine Cycle with an Open Feedwater heater. But the pressure entering the feedwater is given. They want us to select the appropriate pressure value for the system which will then yield the best efficiency. I'd appreciate some help with this. Thank you

Rankine cycle for initially dry saturated steam at 150 psi, condenser pressure of 2 psi. Find the work of cycle in Btu and ft-lb. Also compute the cycle efficiency.Note of the following data from the steam table:At 150 psia: Tsat=358.4 deg. FVf=0.0180 ft3/lb, vg=3.016 ft3/lb; uf=330.2 Btu/lb; ug=1111.2 Btu/lb; hf=330.5 Btu/lb; hfg=863.6 Btu/lb; hg=1194.1 Btu/lb; sf=0.5138 Btu/lbR; sfg=1.0556 Btu/lbR; sg=1.5694 Btu/lbRAt 2 psia: Tsat=126.04 deg. FVf=0.016 ft3/lb, vg=173.75 ft3/lb; uf=94.02 Btu/lb; ug=1051.8 Btu/lb; hf=94.0 Btu/lb; hfg=1022.2 Btu/lb; hg=1116.2 Btu/lb; sf=0.1749 Btu/lbR; sfg=1.7451 Btu/lbR; sg=1.9200 Btu/lbR
1. looking again at problem 1 how would you define the efficiency of the system? whicch components would you ignore? 2. why does the steam need to be superheated before going into the turbine? what negative effects on the turbine might you expect with insufficient heating? 3. for the cycle above, how would you need to modify the cycle to accomodate a lower temperature in the storage layer?
