The figure shows the accepted relationship between drag coefficient and Reynolds number for a smooth sphere. Note that the curve is plotted on a log-log scale. Assume that you perform an experiment to verify this relationship. Your data for C_D^1 vs. Re^2 is shown in the table below the figure. (a) By solving a linear system (Vandermonde matrix), find the polynomial that passes through all x-y data points. Plot the polynomial curve. On the same graph, plot the data points. Note that, ideally for all plots in this problem, you should convert your x-y data back to Re-C_D and plot on a log-log scale using the MATLAB log-log command. Using your polynomial fit, predict the drag coefficient at Reynolds numbers of 100, 10,000 and 1,000,000.

Solution

Reynolds number is an important dimensionless quantity in fluid mechanics that is used to help predict flow patterns in different fluid flow situations. It is widely used in many applications ranging from liquid flow in apipe to the passage of air over an aircraft wing.

the reynolds number is valuble as a guide to the laminar turbulent transition.
