1st law of thermodynamics
dq = du + dw
1 of 8
version 1 of the 1st law
dq = CvdT + pda
2 of 8
what is specific heat at const vol? Value? Unit?
Cv = (du/dT)a const , 717 J/kg/K for dry air
3 of 8
what is specific heat at const pa? Value? Unit?
Cp = (du/dT) p const or Cp = Cv + Rd , 1005 J/kg/K
4 of 8
adiabatic (dq = 0) eqn?
CvdT = -pda or CvdT = adp
5 of 8
isothermal (dT = 0) eqn?
dq = adp = pda = dw , isothermal doesn't have a teperature change
6 of 8
isochoric (da = 0) eqn?
vol is constant, dq = Cv.dT = du
7 of 8
isobaric (dp = 0) eqn?
dq = CpdT = (Cp/Cv).Cv.dT = (Cp/Cv)du
