I'm using Pyhton 3 in Jupyter notebook.

I need to solve this problem with Pyhton 3.

Also, can you explain each code you write?

Problem 4 When computing solutions to the Navier-Stokes equations, we need to define additional models for the thermodynamic and transport properties of the fluid. In realistic CFD applications, a flow is composed of a mixture of gases, and this requires computing mixture-averaged thermodynamic and transport properties. For instance, air at low temperatures is composed of Nitrogen, Oxygen, and trace molecules. One measure used to relate the fraction of molecules in a gas mixture is the mass fraction: YN, = PN2 (12) where p is the total density of the flow and pn, is the density of the Nitrogen. For air (composed of 21% and 79% Oxygen and Nitrogen), the mass fractions are approximately YN, = 0.767 Yo, = 0.233 Assume the internal energy of the gas mixture is provided by the following relationship: IN: e= Cv, mixT = 1 Yncy.n(T)|T (13) Ln=1 where N, is the number of species in the gas mixture, and Co,n is the n-th species specific heat at constant volume, which is a function of temperature. For air, Cair = cvjairT = [YN2Cv,na (T) + Yo,C,02(T)]T (14)
