Derivation of cp and cv
WebApr 7, 2024 · For instance, if a compression stage of one model of the axial compressor is made having a variable, Cp and constant, Cv to compare the simplifications, then the derivation is found at a small order of magnitude. This gives a major impact on the final result Cp. The expression of a calorically perfect gas is generalized as follows: e = CvTh … Web2 days ago · CV (VdP) + CP (PdV) = 0 Dividing both the sides by CVPV, we get: dP/P + (Cp/Cv)* dV/V = 0 We know that Cp / Cv = r dP/P + r* dV/V = 0……. (5) Integrating both the sides in eq… (5) = ∫ dP/P + r ∫ dV/V = C (∵ C, an integral constant) = Loge P + r Logₑ V = C = Loge PV r = C = PV r = ec = PV r = G Adiabatic Relation Between P and T

WebIn a constant volume process, TdS = CVdT, so that T ( ∂ S ∂ P) V = C V ( ∂ T ∂ P) V. And in a constant pressure process, TdS = CPdT, so that (13.4.8) T ( ∂ S ∂ V) p = C P ( ∂ T ∂ V) P. Therefore (13.4.9) T d S = C V ( ∂ T ∂ P) V d P + C P ( ∂ T ∂ V) P d V. This is the third of the TdS equations. In summary, then, these are the three TdS equations: WebThey just differ by nR. So the difference between the heat capacity at constant volume which is three halves nR, and the heat capacity at constant pressure which is five halves nR, is …
