A simple question

Make the equations and geometry dimensionless
Take a low value of the Reynolds number Re in the range 0.001 to 10.
Estimate the pressure drop, and use a rounded off value for inlet pressure. Re-evaluate Re and maximum dimensionless velocity for this pressure.
Delete the existing mesh (grid), and generate a new coarse mesh
Solve the system of equations
Find the maximum (dimensionless) velocity in the main channel (connecting the inlets and outlets).
Repeat the above with two finer meshes. Plot the maximum velocity against the number of elements used. Use the value from the best coarsest mesh that is converged (agrees with the finest mesh).
Compare computed velocity with the estimated velocity
Can anyone please help me with this?
Submit a report with
an x-y plot of Computed Velocity vs Estimated Velocity
Slice plots of the velocity profile in the channel (along with the color code legend) for each of the four Re chosen.
