- Homework Statement
- Determine s1 and s2 given P1= 90.0, P2= 2260.7, T1=283.1, and T2= 711.2

- Relevant Equations
- P1= 90kpa

T1= 283.1K

v1/v2=10

P2=P1(v1/v2)^k= 90(10)^1.4= 2260.7kpa

T2=T1(v1/v2)^(k-1)= 283.1(10)^0.4= 711.2K

Hello, just wanted to ask regarding the otto cycle; if we were to find the entropy at the phase of isentropic compression and I was already able to derive the temperature 1 and 2 and the pressures at 1 and 2 and I also have the compression ratio of 10. How do I derive the entropy (s1 and s2)? given the fact that entropy at this phase is s1=s2.
