First you selected a gas-turbine power plant operating on an ideal Brayton cycle and according to the manufacturing datasheets it has the following specifications: • A pressure ratio of 10. • Heat is added to the cycle at a rate of 500 kW • Air passes through the engine at a rate of 1 kg/s • The air at the beginning of the compression is at 70 kPa and 0 C. Task 1 Investigate the principles of operation for a gas turbine power plant by considering the following: 1. Construct T-S and P-V diagrams while discussing the operation of a gas turbine power plant 2. Describe the difference between closed and open gas turbine engine 3. Explain how a closed gas turbine engine would be combined with a steam power plant. 4. Explain why Brayton cycle is more preferred over Rankin cycle in power plant stations? And how would you enhance the performance of a Brayton cycle?

Task 1
Investigate the principles of operation for a gas turbine power plant by considering the following:
1. Construct T-S and P-V diagrams while discussing the operation of a gas turbine power
plant
2. Describe the difference between closed and open gas turbine engine
3. Explain how a closed gas turbine engine would be combined with a steam power plant.
4. Explain why Brayton cycle is more preferred over Rankin cycle in power plant
stations? And how would you enhance the performance of a Brayton cycle?
