Problem 09.097 - Modified Brayton Cycle with Two-Step Expansion - DEPENDENT MULTI-PART
PROBLEM - ASSIGN ALL PARTS
A gas-turbine power plant operates on a modified Brayton cycle shown in the figure with an overall pressure ratio of 8. Air
enters the compressor at 0°C and 110 kPa. The maximum cycle temperature is 1500 K. The compressor and the turbines
are isentropic. The high-pressure turbine develops just enough power to run the compressor. Assume constant properties
for air at 300 K with cy= 0.718 kJ/kg-K, cp= 1.005 kJ/kg-K, R= 0.287 kJ/kg-K, and k = 1.4.
