Question
Q1/ A gas turbine operates with components as shown in figure 1. Air enters this
first compressor at 96.5 kPa. and 15.5°C; the pressure ratio is 3 for each stage of
compression; the air temperature when entering a turbine is 504.5°C; and the heat
perfect exchanger. (Take air index as 1.4 and specific heat as 1.005 kJ/kg.K).
Draw T-S diagram and determine:
a. The air mass flow rate, and the rates of heat addition and rejection when this
produced power is 745.7 kW.
b. What will be the effect of using normal heat exchanger on the thermal
efficiency?
