Task (1)
A Brayton cycle with regeneration operates with a pressure ratio of 7. The minimum and maximum
cycle temperatures are 300 K and 1000 K. The isentropic efficiency of the compressor and turbine
are 80% and 85%, respectively. The effectiveness of the regenerator is 75%. Use constant specific
heats evaluated at room temperature.
Part 1
A. Show the cycle on a T-S and P-V diagrams if applicable.
B. Discuss the operation of a gas turbine power plant.
C. Determine the air temperature at the turbine outlet.
D. Calculate the Back-work ratio.
E. Determine the net-work output of the cycle.
F. Calculate the thermal efficiency of the cycle.
G. Now assume that both compression and expansion processes in the compressor and
turbine are isentropic. Calculate the thermal efficiency of the ideal cycle.
