Question
A closed cycle is executed with helium as the working fluid. The flow rate through the device is m in = 1 kg/s.
The cycle consists of four processes:
1→2: Reversible, adiabatic expansion from 300 kPa, 300 K to 100 kPa,
2→3: Reversible, isobaric heat transfer to double the specific volume (i.e., v3/v2 = 2)
3→4: Reversible, adiabatic compression back to the original pressure
4→1: Reversible, isobaric heat transfer back to the original state
a) Complete the following table and mention what state helium is in each step
