Transcribed Image Text:The air entering the turbine with 1200 K and 1200 kPa expands to 100 kPa pressure in two
stages. When the air is reintroduced to 1200 K at a constant reheat pressure of 350 kPa and
both expansion stages are ideally realized:
a) Total expansion work (kJ/kg)
b) Intermediate heating amount (kJ/kg)
c) Calculate the rate of increase in work according to the stepless (without reheating)
expansion.
Features for air:
k=1,4, R=0,287 Jkg K,F1,005 klkg K
k = 1.4
R = 0.287 kJ/kgK
