WebOct 12, 2005 · The Cp/Cv value in Hysys is the 'actual' value, based on the equations of state in thermodynamic package you are using. You can calculate the 'ideal' value by the following formula: Cp/Cv (ideal) = Cp / (Cp - R) where Cp = molar heat capacity of gas stream (kJ/kmolK) R = universal gas constant = 8.314 kJ/kmolK. WebOne cubic meter of an ideal gas at 600 K and 1000 kPa expands to five times its initial volume as follows: (a) By a mechanically reversible, isothermal process. (b) By a mechanically reversible, adiabatic process. ... Starting with the definition of κ, \kappa, κ, show that the path of the process is described by: ...
WebNov 15, 2007 · The equation K=Cp / (Cp-R). is valid only for a perfect gas. Try what MortenA suggests or go use an equation of state combined with the low pressure specific heats to get K. Regards. 25362 (Chemical) 13 Nov 07 08:12. Cp-Cv = T (∂P/∂T) V (∂V/∂T) P, which for an ideal gas results in Cp-Cv = (TR/V) (R/P) = R. Applying the Berthelot ... WebFrom the ideal gas law, P V = nRT, we get for constant pressure d(P V) = P dV +V dP = P dV = nRdT . Substituting this in the previous equation gives C p dT = C V dT +nRdT . Dividing dT out, we get C P = C V +nR . For an ideal gas, the heat capacity at constant pressure is greater than that at constant volume by the amount nR. 2
WebDec 23, 2024 · When a system of ideal gases reacts, Cp and Cv are changing, but not their difference. I think.....while deriving this equation we use ideal gas equation PV=nRT which … WebQ: (c) An ideal monoatomic gas at 1 bar and 300 K is expanded adiabatically against a constant pressure… A: (iii) Given Cv=1.5R=3/2R Cp-Cv=R Cp=R+1.5R… Q: Three moles of …
WebAs a throttling process as previous shown is an isenthalpic process (h=constant) (from the 1st law), and as the enthalpy for an ideal gas is only dependent on the temperature (dh=cp dT), we know that the temperature is also constant for the throttling process: ℎ 1 = ℎ 2. 𝑇𝑇 1 = 𝑇𝑇 2
