1. Air enters the compressor of an ideal air-standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5 m 3 /s. The compressor pressure ratio is 10. The turbine inlet temperature is 1400 K. Determine (a) the thermal efficiency of the cycle, (b) the back work ratio, (c) the net power developed, in kW. Draw a detailed PV and Ts diagram Note: For AIR, use c, =1.0062 kJ/kg-K, R = 0.287 KJ/kg-K

Question
1. Air enters the compressor of an ideal air-standard
Brayton cycle at 100 kPa, 300 K, with a volumetric
flow rate of 5 m 3 /s. The compressor pressure ratio
is 10. The turbine inlet temperature is 140 K.
Determine (a) the thermal efficiency of the cycle,
(b) the back work ratio, (c) the net power
developed, in kW.
Draw a detailed PV and Ts diagram
Note: For AlR, use
Cp =1.0062 kJ/kg-K, R= 0.287
KJ/kg-K
