Thermodynamic Equations
Isentropic Temperature Relation
T2 = T1 * (P2 / P1)^((k-1)/k)
Volume Ratio Relation
V2 / V1 = (P1 / P2)^(1/k)
Isentropic Work Done (w)
w = Cv * (T1 - T2) = R * (T1 - T2) / (k-1)
Adiabatic Index (k): 1.4.
Work output: -125.7 kJ/kg of gas. A negative value indicates work input (compression).
