QUESTION 2

Kindly answer correctly. Please show the necessary steps. Thanks in advance.

Question 2
The figure below shows a gas turbine which draws in air from the atmosphere at 1 bar and 10 °C and
compresses it to 5 bar with an isentropic efficiency of 80%. The air is heated to 1200 K at constant
pressure and then expanded through two stages in series back to 1 bar. The high-pressure turbine is
connected to the compressor and produces enough power to drive it. The low-pressure turbine is
connected to an external load and produces 80 kW of power. The isentropic efficiency is 85% for both
stages.
=
Take Cp 1.005 kJ/kgk and y = 1.4 for the compression process, and Cp = 1.149
kJ/kgk and y = 1.333 for the expansion process.
