Task 6: In a steady-flow closed-cycle gas turbine engine shown in figure 2, the temperature and velocity of the working fluid (air) between the various components are as follows: Cooler and compressor: Compressor and heater: Turbine and cooler: [A]C, 90 m/s; Fuel Air Exhaust gasos [C]C, 100 m/s; Heater System boundary [B]C, 30 m/s; The velocity of the air entering the turbine is 300 m/s and the heat transfer to the air in the heater is [D] kJ/kg. All heat transfers to the atmosphere may be assumed to be negligible. Calculate: (a) The temperature of the air at entry to the turbine, (b) The heat transfer from the air in the cooler, (c) The net work output of the plant, (d) The efficiency for the gas turbine engine, Compressor Turbine W out Cooler Coolant Figure 2 (e) Critically analyse the changes in the thermal efficiency of a heat transfer process can affect the behavioural characteristics of the gas turbine engine shown in figure 2.
