b) Derive the steady one dimensional convection diffusion equation in discretized form.

problem 6)a) Brine solution of Specific Gravity of 0.9 is flowing in a square duct of side 25 mm. It enters the duct with a temperature of 60°C. The velocity of flow is assumed to remain constant at 8 m/s. The diffusive flux (Γ) through the duct can also be assumed to be constant at 800 kg/m/s. The length of the duct is 900 mm. Exit temperature of the solution is 20°C. Apply the following discretization schemes and obtain the temperature distribution along the duct. (1) Central Difference Scheme (CDS) (2) Upwind Differencing Scheme (UDS).Use three equally spaced grids to descritize the domain.
