Q3
- a)[9]
The air enters the compressor of 5 MW capacity gas-turbine power plant at1bar, 30 degrees Celsius. The maximum cycle temperature, pressure is 550 degrees Celsius, 5 bar respectively. The two stage expansion with reheating pressure of 2.24 bar is used in the plant. In the re-heater gas is heated up to maximum cycle temperature. The gases are expanded up to 1 bar in second turbine. The isentropic efficiency of compressor, both turbines is 80%, 85% respectively. Take adiabatic index for air gas as 1.4,1.33 respectively. Take specific heat for air, gas as 1 kJ/Kg-K, 1.15 kJ/Kg-K respectively. Neglect mass flow rate of fuel. Draw cycle arrangement and T-s diagram and determine i) The thermal efficiency of cycle ii) Mass flow rate of air

Q4
- a)[9]
Air enters the compressor of a gas.turbine power plant having capacity 10 MW at 1 bar and 27 degrees Celsius. The maximum cycle temperature, pressure is 577 degrees Celsius, 6.5 bar respectively. The two stage compression with perfect inter-cooling arrangement is incorporated in the plant. The compression in both stages and expansion in turbine are isentropic. Take adiabatic index, specific heat for both air and gas as 1.4,1 kJ/Kg-K respectively. Assume calorific value of fuel as 45 MJ/Kg. Draw cycle arrangement and T-s diagram and determine i) The thermal efficiency of cycle with considering effect mass flow rate of fuel on air. ii) Fuel consumption on per hour basis (with inter-cooling arrangement)
