Question

I need help with these 2 problems and all of their parts. 

Combined cycle power plants are common because of their high efficiency and scalability. They typically combine a
gas turbine cycle (the Brayton Cycle) with a steam turbine cycle (the Rankine Cycle) [1]. This project is to determine
the operating efficiency and profitability of a realistic combined cycle power plant. The power plant is as follows:
1. A natural gas-fired Brayton Cycle with mair,Br = 0.72 kg s.
(a) Ambient air at 1.00 bar and 300 K is taken in.
(b) A compressor with an inlet-to-outlet pressure ratio of 1:19.
(c) Intercooling, decreasing the temperature by AT = -150 K.
(d) A second-stage compressor with a pressure ratio of 1:5.
(e) Regeneration between the compressor and the combustor, increasing the temperature by 85 K
(f) Combustion at constant pressure to 1800 K.
(g) A two-stage turbine system with reheat between the stages. Reheat occurs at 12.4 bar and raises the
temperature to 1600 K.
(h) Discharge to a heat exchanger at 1.50 bar, where waste heat is used to warm steam for the Rankine Cycle.
The outlet temperature from this heat exchanger is 600 K.
(i) From that heat exchanger, discharge to the regeneration heat exchanger in part le.
2. A water-steam Rankine Cycle with mwater,Ra = 1.06 kg s-1.
(a) A two-stage turbine system, with reheat between the stages.
The first turbine inlet is at 560 °C and 160 bar. Reheat occurs at 40.0 bar up to 52o °C. The second-stage
turbine outlet is 2.00 bar.
(b) Cooling at constant pressure in a condenser via heat exchange with ambient air to saturated liquid.
The air used in condenser cooling must not exceed 400 K when it is released from the power plant.
(c) A pump from the low-side pressure to the high-side pressure.
(d) Heating in a boiler at constant pressure, using the waste heat from the Brayton Cycle in a first stage and
natural
in the second stage.
