A power cycle for a piston-cylinder device is described by the following four processes:
1→2 Isothermal compression from T1 = 300K, P1 = 100 kPa to P2 = 600 kPa.
2→3 Constant pressure heat addition until the temperature is T3 = 800K.
3→4 Isentropic expansion until the volume at state 4 equals the volume at state 1.
4→1 Constant volume heat rejection until the temperature is 300K.
Assume the working fluid is an ideal gas with constant specific heats and has properties as follows: CV = 0.600 kJ/(kg-K), CP = 0.900 kJ/(kg-K), R = 0.300 kJ/(kg-K), k = 1.500.
(a) Sketch the P-v diagram for this cycle
(b) Sketch the T-s diagram for this cycle
(c) Determine the heat rejected during process 1→2, in kJ/kg.
(d) Determine the heat added during process 2→3, in kJ/kg.
(e) Determine the total cycle expansion work done by the gas, in kJ/kg.
Could you please fill in this table, this will help organize all of the processes.
