Beneral Be the expressions for p, r, and S? 2.7 Consider a mixture of various chemical species. Define the mixture enthalpy by h = Emihy, where my is the mass fraction of a typical species, and hy is its specific enthalpy, which is given by T hy=hi + $ ci d , 0 Here hi is a constant, and c, is the constant-pressure specific heat of species 1. Write the steady-state enthalpy-conservation equation and hence show that p=h, r = k/c, and S=Sn + div ((r, klc)h, grad mil, where c is the mixture specific heat, given by smici.
