This is a Diesel cycle
Ideal gas model, constant specific heat
R= 0.287 kj/kg-k
Cv = 0.717 (kj/kg-k)
Cp=1.004 [ kj/kg-k)
gamma = 1.4
find entropy at each state s (kj/kg-k)
at state 1
P1=200Kpa
T1 =300K
at state 2
P2=7000KPA
T2=828.48K
at state 3
P3=7000KPA
T3=1500K
at state 4
P4=459.16Kpa
T4=688.74K
Example
@stATE 1
p1= 95 KPA
t1 = 290K
ANSWER : s1 = 1 kj/kg-k
