Problem # 3 [24 Points] Property Information A regenerative gas turbine with intercooling and reheat operates at steady state. Air enters the compressor at 100 kPa, 300 K with a mass flow rate of 5.807 kg/sec. The pressure ratio across the two-stage compressor is 10. The intercooler and reheater each operate at 300 kPa. At the inlets to the turbine stages, the temperature1400 K. The temperature at the inlet to the second compressor is 300 K. The isentropic efficiency of each compressor stage and turbine stage is 80%. The regenerator effectiveness is 80%. Given: P₁ = P9 = P10 = 100 KPa P3300 kPa 1st = 80% nsc = 80% m = 5.807 kg/sec Engineering Model: 1- CV-SSSF 2 qt=qc=0 3 - Air is ideal gas. 4 - AEk,p= 0 h2 = h₁ = 300.19 kJ/kg h2s = 411.3 kJ/kg _kJ/kg h3 = P2 P4 kJ/kg h4s = 423.8 kJ/kg kJ/kg kJ/kg h4 = h5 = T1=T3 = 300 K Ts 1400 K P8 = 300 kPa T6 P5 P6 = 1000 kPa P7 Property Information: h6 1515.4 kJ/kg h7s = 1095.9 kJ/kg kJ/kg h7 = kJ/kg h9s = 1127.6 kJ/kg kJ/kg kJ/kg h8 = h9 = h10 =
