A few are derived in examples here. Example 3.4 Derive the expression h = u + P/ρ. Start from the equation for the constituent hi , multiply by mass fractions, sum over all species, and use properties of mixtures: Pi , ρi hi = ui + ci h i = ci u i + ci ci h i = (3.203) Pi , ρi N N N N (3.205) ci ρi Ri T , ρi (3.206) N ci u i + = i=1 Pi , ρi i=1 N ci h i ci ci u i + i=1 i=1 (3.204) i=1 i=1 =u =h N h = ci Ri , u+T (3.207) i=1 =R = = u + RT, (3.208) P . ρ (3.209) u+ CC BY-NC-ND. 18 November 2011, J.
