A gas turbine power plant operates on a simple thermodynamic cycle. The ambient conditions

are 100 kPa and 24 °C. The air at this condition enters the engine at 150 m/s whose diameter
is 0.5 m. The pressure ratio across the compressor is 13, and the temperature at the turbine
inlet is 1400 K. Assuming ideal operation for all components and specific heats for air and
products separately. In addition, neglect the mass of fuel burned. Do the followings:

a) Choose the suitable thermodynamic cycle “Brayton Cycle”

b) Draw pv and Ts diagram and label it

c) Calculate the power required by the compressor

d) Determine the pressure and the temperature at the turbine exit

e) Compute the power produced by the turbine

f) Available specific work

g) The thermal efficiency.
